Questions Answers
Can you expand more on the symptoms? Was there something in particular that you should have paid more attention to? The symptoms were just like the symptoms for diverticulitis which are an abdominal pain as if someone was stabbing you in the belly button, and constipation. This time though was different as I had an additional pain in the area of my appendix, and that area doesn't normally suffer from diverticulitis, at least not in my experience.
I had been told by doctors in the past that I should have the colonoscopy due to my diverticulitis but I never went because I didn't want a camera shoved up my ass.
And here is where it gets really eff'd up. Colon cancer can take as long as 10 years to fully develop to stage 4, and if I had gotten the colonoscopy, they may have caught it at stage 2 or 3 and I would have been ok, so in a sense I feel as if I have committed suicide by my own inaction. :-/
How was your diverticulitis diagnosed? I'd be very skeptical of diagnosing diverticulitis in a 40-yo person WITHOUT a colonoscopy, or at least a barium enema. Diverticulitis is something we see in the elderly. I developed diverticulitis probably around age 35ish. The diverticulitis would always show up on the CT scans in the transverse colon, and I could be incredibly wrong here, but I do believe colon cancer starts in the ascending colon which is on your right side around the area of the appendix.
It's my assumption that I had diverticulitis symptoms, including pain in the transverse colon, because the stage 4 tumor had grown so large that it had started to block off "the poop train" which in turn caused a back up of fecal matter which started to become impacted and caused the diverticulitis inflammation.
You are so brave for doing this and will no doubt help someone reading this - thanks! If the tumors are shrinking, why isn't it possible to become cancer free after so much time on chemo? Does it always come back eventually? Thanks. :-) It's kinda therapeutic to talk about it.
I get blood work every other week, and in that blood work they look for a cancer marker called CEA or Carcinoembryonic antigen. This marker shows how active the tumors are.
Before I started chemo, my CEA was something like 2600, and through chemo I was able to reach a CEA of 146. I then took a break from chemo just so I could feel human again, and my CEA shot up from 146 to 292 so I will never be cancer free, and I will have to take chemo until die.
Cancer has 4 stages, I was diagnosed as late stage 4. When you get diagnosed with pretty much any late stage 4 cancer, you are fucked and there is no way out.
Because the cancer metastasized, it spread to my liver and the lining of my internal organs. These 2 locations are inoperable, and the chemo is there just to manage the cancerous tumors, not to cure them.
What will more than likely happen is that eventually my body will reject all of the chemo drugs, the tumors will awaken, and I will have maybe a year to say my goodbyes.
Um...sure...what did you want to know? I'm curious as to what brought on her death other than the cancer of course. Did her body just give up on the chemo, and the tumors started to grow again? And what symptom did she actually die of? Was it the eventual liver failure?
How was her pain in the end? Was she referred to hospice? If so, how was her level of care? Was there a lot of pain for her in the end, or did drugs take care of that?
How old are you? Also have they given you better odds/more time since you've responded well to chemo? I turned 45 on June 2nd. It's possible that I may live beyond 5 years, my oncologist has a patient that has made it to 10 years, but my cancer was at such an advanced stage that it's hard to tell.
If I keep having allergic reactions to the chemo, they will have to either try something else or take me off chemo completely, at that point the 1 year clock starts ticking.
I hope things go as good as they possibly can man. Just make sure you tell that little girl how much you love her every day. Please feel free to ignore this question if you are not comfortable with it, but do you think you'll opt out of chemo eventually (quality vs quantity)? Oh man, I can't tell you how many times I've thought about opting out of the chemo.
Chemo was REALLY bad at first. I had horrid nausea, I couldn't eat for up to 3 days afterwards and I pretty much spent those days in bed.
Things are much better now that my body is used to the chemo, and I have a somewhat better attitude towards this whole thing.
I'm a huge fan of electronic music and I'm thinking about getting FL Studio so that I can make some music in order to exorcise these demons so to speak.
Edit: Thank the cosmos for marijuana, it got me through some of the really bad chemo session aftereffects.
Good stuff man. Spend your time doing what you love. Nothing inspires me to live more than the fact that I know I will die, and could on any given day. One of the messed up things about this is that now I've been diagnosed, I have this new insane desire to learn how to create music and put out some quality work before i croak, but I'm not sure I'm going to have enough time.
How do you want your family to treat you as time goes? I just want them to treat me as they do now, they all know what's up, and are very supportive.
What are your aspirations and dreams for your daughter's life beyond yours? My aspirations for my daughter are for her to be whatever she wants to be. I would want her to do whatever makes her happy. If she were to feel an attraction for the same sex then go for it, I'm an atheist and I've never introduced her to any religion, but if she discovers it on her own, I wouldn't discourage her no matter what my views are. I would just want her to be happy no matter what she does and she would have my full support no matter what short of becoming a hooker. :-)
Have you and your doctors explored any trial treatments? I live in Pittsburgh, PA and there's a huge medical presence here with the University of Pittsburgh Medical Center. They may have new alternative treatments, but my oncologist and I have never discussed that.
I'm an atheist. Is it tempting to believe in an afterlife now that you're staring death in the face? Not really. I believe that when I die, everything will just go black.
Have you told/are you planning on telling your daughter any details of your diagnosis, including how long the doctors have predicted you have left to live? My daughter is too young to understand right now. I've told her about some things because she has seen my chemo pump, but she just says "oh" and keeps playing with her princess dolls. :-(
I just hope you get to see your daughter grow up. Stay strong! Yes! Start by having a colonoscopy performed. They say to start getting them at age 30. If your regular doctor can't get them approved through your medical insurance, they can more than likely get them approved by referring you to a specialist.
Now, is there anything that can be done to find that particular kind of cancer early in its developement? It is so frightful to think the tumor can spread during ten years, going unnoticed, and yet there is no possibility to catch it before it is too late. Even if you get to stage 3 cancer, they can pretty much get rid of it via a surgical procedure. When it reaches stage 4 it has already begun to spread to other areas that may not be operable.
Have you used medical marijuana? I've used MJ, it's just not medical here in PA.
Just a thought, but because marijuana should be legal if you want to get medical marijuana delivered to you try /silkroad. It would be a public relations nightmare to ever prosecute you, if by the minuscule chance you ever got caught. How long does it take to generate enough BitCoin to place an order?
Does cancer hurt at all, like the effected area? Does it have any outer sign? And hope you're ok man. The cancer never really caused me much pain in the beginning except for some soreness. Even though I still had tumors on my liver and peritoneum after my surgery, it's hard to say whether or not they started to give me pain because I had all kinds of pain from my colon resection and my abdominal scar.
I'm assuming if the cancer had grown even more and spread to other organs, that I would have started to experience some pretty bad pain.
Do they think this was in some way connected to your diverticulitis? Probably not. It is more than likely hereditary because my grandmother died from it in 1980.
Have you found people awkward around you, and if so do you wish they would treat you like normal? Btw, I wish you all the very best in your treatment and I hope the doctors are being on the pessimistic side wirh your prognosis! xx. Thank you for the well wishes. :-)
People pretty much treat me as they always have. I had a shit ton of support from friends, family, and even co-workers so that part of this ordeal has been really positive.
What's on the bucket list? Spend more time with my daughter and family.
Trip to Amsterdam.
Trip to Hawaii.
Find someone to love that doesn't care about my cancer status.
To not die until age 80 at least.
Build a new gaming PC that will crush current and near future games.
These are just a few. I may add some more later.
What's your monetary situation like? I am unemployed now due to disability, I was a deli clerk at the time of diagnosis. I applied for SS disability income, but it took 5 months for them to grant it to me because that is the waiting period from the time your disability. What I get is not much and it's almost laughable seeing as how they expect me to pay my bills, eat, and provide my own medical insurance.
You don't get Medicaid or Medicare since you're on disability? It takes 2 years from the time disability starts before you are eligible for medicare.
That sucks. Yeah. You wouldn't believe the bullshit I've been going through trying to get government aid. For instance, I'm unable to get approved for public assistance medical care because I make too much $$ from my SS disability, but public assistance has this MAWD program that allows me to work a few hours here and there so I can be eligible for medical insurance at a cost of 5% of my SS income.
So let me clarify. I am ineligible for medical assistance from the state because I make too much $$ from the feds, but if I make a little more $$, I am eligible for medical assistance for 5% of what I make from SS income.
Does that make sense? Doesn't that just boggle the mind?
What is your family history like with colon cancer? My grandmother (age 83) and aunt (age 60) bother passed away in the last two years and my mother (age 56) also had a polyp removed about a year ago. I often worry about my risk with developing the cancer. Stay strong and never give up. My grandmother died from it in 1980. It had metastasized to her uterus, and she died shortly after having her uterus removed.
Get yourself genetically screened, and if you DO carry the gene, get your kids screened ASAP so you can plan for the future in regards to their healthcare.
Hi. first off, i want to say good luck, and thank you for doing this. my biological mom died from colon cancer 2 years ago (at age 44), before i got to connect with her. she too was diagnosed at stage 4 and didn't make it more than 2 years. i believe the chemo wasn't working for her, and based on some things she wrote that i got to read recently, it seems like she was not happy with her oncologist. Are you happy with your oncologist? I am VERY happy with my oncologist and her team of nurses at my care center. I actually look forward to going there sometimes because I know I am being well cared for, and sometimes I even flirt with the nurses. ;-) My grandmother died of colon cancer in 1980, so I believe my cancer is hereditary. I will be going to get screened for the cancer causing gene and so will my daughter so that in the future, she will be able to be proactive about cancer detection if she also carries the gene.
I am at work and I nearly cried reading this. The part where you mention you kid, my coworker literally asked why I was blinking so much. How old were you when you found out? What are you going to do for your kid if something goes wrong soon? Did you go through any depression or anything? I had already been diagnosed with severe depression in the past, and my diagnosis really agitated it.
My daughter doesn't live with me, my wife divorced me a year and a half after she was born. My daughter is and always will be well cared for.
Why are you just on chemo and not radiation? Is radiation only for certain cancers? Can't answer that for sure, but I would assume that if radiation therapy would have been the way to go, they would have used it on me.
I'm really sorry to hear about your condition. Our family also lost a loved one a year ago to this horrible disease. As a religious family, we found strength in our beliefs knowing that what is to come is better than all that will be left behind. Do you ever think about religion? I mean, are you more open now to the possibilities of there being a God? I am an atheist and have been for some time. My illness has changed nothing in regards to my atheism.
Have people, even those who know you're an atheist, tried talking to you about their respective religious beliefs? For example Christians talking to you abut Jesus and how he can change your life? My mother is the only person in my life that tries to talk to me about god and jesus, and I tell her that I don't believe in it. She doesn't get it, she thinks that I do because as I grew up I was exposed to and brainwashed by those beliefs. There is no god, there is no jesus, and those are my beliefs.
What have your dietary habits been like? At first I couldn't eat much, everything tasted nasty and extra salty plus my tongue had this weird almost metallic flavor on it all the time. I lost 46 lbs in 2 months.
I now have my appetite back, I'm enjoying my favorite foods, and I've begun to put weight back on.
I've been going back and forth with diverticulitis since about this time last year. Currently have an ileostomy, going to get a resection of my lower colon hopefully sometime soon. How good is hydrmorphone by the way? OMG dude, Hydromorphone/Dilaudid is an incredible pain killer, and I'm serious when I say that after they juice you with it, they could come, cut your legs off, show them to you, and you wouldn't give a fuck.
Haha tell me about it. I had a PCA of it and could hit the button every 10 min. Twas fantastic. I had one of those buttons too, but eventually my body started to "reject" the painkiller, and I began to have an hour long vomit session everyday where I puked up this weird dark green watery liquid.
They ended up taking me off the pain pump about a day before I left the hospital.
You may not know the answer to this question (and you may not even be answering questions anymore), but do you know the likelihood of inherited colon cancer? My paternal grandmother (and her mother) were both diagnosed with colon cancer. How on top of my health should I be? I'm not sure. Sorry.
Now that the tumours are gone, does this mean you're not going to die? No, they are just sleeping right now. If I were to stop chemo, they would awaken, and I would be dead within a years time.
What is your favorite color? Blue.
Do people not take colon cancer as seriously as they may some other cancers? Not sure what you mean by this.
UPMC or WPAHS? UPMC.
So sorry to hear. My mother had colon cancer, also spread to her liver. She was diagnosed in Sept 2008. She had her ups and downs, but was mostly pretty ok. Sadly, she passed in January of 2012. Keep fighting and enjoy the time you have! Would you mind answering a couple of questions? I'm curious about how my end will come about.
Good luck. I am a 6 yr survivor of stage III colon cancer. I took 11 rounds of Oxi, that was rough stuff. Nearly killed me. I hope you have joined the Colon Club online. Great support and info. Oxi as in Oxailiplatin?
Yes. That stuff is nasty. I now have neuropathy in my finger tips from the Oaxiliplatin. Sometimes it's hard to pick up very small objects because I can't feel them. I'm no longer on Oxi because I started having allergic reactions to it by breaking out in hives, and having extreme shortness of breath.
I had the shortness of breath one day while getting treated so they mainlined Benadryl into me. The Benadryl pretty much turned me into a zombie for the next 2 days.
Don't blame yourself. You could never have seen this coming. I do blame myself somewhat because if I had gotten the colonoscopy during my diverticulits issues, they would have seen the cancer in it's early stages.
I don't really have a question but I wish you all the best. I hope your health defies your prognosis and you get more precious years with your daughter. Thank you for your well wishes. :-)
Let your kids know your history so they get early checkups. My Dad beat it and because of the history (it's largely genetic) I get checkups every 5 years starting at 40 and they have caught early pre-cancers on Polyps etc but I'm in good shape. Since it's possible that this is hereditary, my grandmother died from it, I'm going to get genetically screened, and then have my daughter do the same so that if she does carry the gene, at least she can be proactive and save herself during her adulthood..
MERRY CHRISTMAS! :D but seriously man, best of luck, I know you'll pull through. Thanks. And I appreciate the Christmas comment because when I tell my story to people, I kinda crack a joke about me getting cancer for Christmas.
I try to put a little humor in it because if I don't, my mind will destroy me with thoughts of death, and me leaving my daughter behind.
The way things are going with cancer research now, you may not have to live the rest of your life on chemo. Stay strong and be the best dad you can be. That's good to hear, and thank you. :-)
My grandma got the same diagnosis you did! Stage 4, 3-5 with chemo. Hers was pretty bad too, no colon to save, spread to hip bones, softball sized tumor, needed a hysterectomy and more. Been in remission 4 years already, and if you know better than my grandma don't smoke and listen to your doctors! Is she in remission with or without chemo?
Try Rick Simpson Oil. I know there are skeptics here that STILL believe there is no scientific evidence to back it up that it cures, but there are studies and testimonies of the oil treating the cancer. Hell, Dr. Gupta from CNN even said it works! www.phoenixtears.ca to get you started. I've heard about this guy. I live in a state that does not have medical cannabis. I'm not sure if I'd be willing to risk bringing back cannabis oil across the border. I do however consume regular MJ via my MFLB or glass here when I can get it.
Thanks for the link though, I'll definitely read it.

Technical: Taproot: Why Activate?

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

How long does it take for my balance to unlock?

Your balance is unlocked after 10 confirmations (which means 10 mined blocks). A block is mined approximately every two minutes on the Monero network, so that would be around 20 minutes.

How can I prove that I sent a payment?

The fastest and most direct way is by using the ExploreMonero blockchain explorer. You will need to recover the transaction key from your wallet (complete guide for GUI / CLI).

How do I buy Monero (XMR) with Bitcoin (BTC)?

There are dozens of exchanges that trade Monero against Bitcoin and other cryptocurrencies. Check out the list on CoinMarketCap and choose the option that suits you best.

How do I buy Monero (XMR) with fiat?

How can I quickly exchange my Monero (XMR) for Bitcoin (BTC)?

There are multiple ways to exchange your Monero for Bitcoin, but first of all, I'd like to remind you that if you really want to do your part for Monero, one of the simplest ways is to get in touch with your merchant/service provider and request for it to accept Monero directly as payment. Ask the service provider to visit the official website and our communication channels if he or she needs help with system integration.
That being said, the community has been recommending two services in particular, XMR.TO and MorphToken. These services are only recommendations and are operated by entities outside the control of the Monero Project. Be diligent.

How do I mine Monero? And other mining questions.

The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.

2. Wallet: CLI & GUI

Why I can't see my balance? Where is my XMR?

Before any action there are two things to check:
  1. Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
  2. Is your wallet fully synchronized? If it isn't, wait the sync to complete.
Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized.
You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait.
If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.

How do I upgrade my wallet to the newest version?

This question is beautifully answered on StackExchange.

Why does it take so long to sync the wallet [for the first time]?

You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization.
Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).

I don't want to download the blockchain, how can I skip that?

The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld.
Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy. A remote node can't see your balance and it can't spend your XMR.

How do I restore my wallet from the mnemonic seed or from the keys?

To restore your wallet with the 25 word mnemonic seed, please see this guide.
To restore your wallet with your keys, please see this guide.

3. Wallet: Ledger

How do I generate a Ledger Monero Wallet with the GUI or CLI?

This question is beautifully answered on StackExchange. Check this page for the GUI instructions, and this page for the CLI instructions.

4. Nodes

How can my local node become a public remote node?

If you want to support other Monero users by making your node public, you can follow the instructions on MoneroWorld, under the section "How To Include Your Node On Moneroworld".

How can I connect my node via Tor?

This question is beautifully answered on StackExchange.

[ Bitcoin ] Technical: Taproot: Why Activate?

Topic originally posted in Bitcoin by almkglor [link]
This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given private key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

My stock study watchlist. would appreciate criticisms or red flags

Core
- FB ecosystem
This is the stock that i believe is invested in the right places and has a path forward in the global market. I work as a React developer in fintech and I greatly enjoy their technology. The reason I stopped using snapchat was because I couldn't use it on low connection in Mexico, but Instagram worked marvelously. I use Whatsapp to stay in touch with my family in mexico and Facebook to stay in touch with my mom. There's something extremely powerful about that in my opinion.
They're conservative with their push and development of camera and VR technology which is wise in my opinion give the many opportunities that exist in that space. They're pushing along with fintech in India, again with small business through Whatsapp. And they provide a suite of customer services for small business and entrepeneurs.

- Microsoft
I think they will have a great run during the cloud era of software development. Their acquiring of Github AND NPM goes to show how in touch they are with developer servicing.

- Paypal
Paypal has a marvelous history and is a battle tested pioneer in the fintech space. I see them repeating their previous successes by acquiring Honey. I work with Honey in the fintech space and now I'm understanding that Paypal has an auto coupon scraper on my Amazon purchases while my Visa ones don't. This is the forward thinking I love from Paypal despite not being as flashy as Square.

- Disney
Disney is quintessential american entertainment. I believe their deep roots in American culture and the entertainment industry will provide a solid bedrock for them for the generations to come.

- Waste Management
Sanitation and environmental, like internet connection technology, are about the same when it comes to market penetration. It is a scarcity. Sanitation is a critical part of any society's development and wellbeing. I think WM will be there to benefit from increased urbanization and industriousness from technology and wealth growth.

- Kansas City Southern
I'm Mexican and my family are avocado farmers. I believe in the future prospects of Mexico and its relationship with its neighbors. Mexico is a bustling nation and many youth are international students that carry degrees. This is a far cry from having military policing streets in rural neighborhoods decades ago. Kansas city southern is part of the supply chain that connects Mexico to main industrious Mexican states like Monterrey, Jalisco, and Michaocan. I like rail in this regard because it's a lot of weight in one operation of heavy materials. So Canadians that use Mexican mining will also benefit from this railroad.
- Nintendo
I believe in the future of gaming as a market and if I were to take a shot at who would be the most stable, I would vote for Nintendo. Like Facebook, they approach the family unit and grow generationally. I love their curveball approach to gaming and I think that creativity, along with it's customers trust, will be something I can hold onto for a long time versus companies that have a history of developing games like Call of Duty or World of Warcraft. Nintendo can take different forms: in the living room, at sweaty tournaments, online, mobile, on your phone, on a TV, in the movies, etc.

Closely watching
- United Health or Cigna
This is only going to grow and wont change due to American politics for 8 years at a minimum.
- Cisco
Same as Microsoft but for IT.
- Impossible Foods IPO
I've been vegetarian for 10 years and Impossible Burgers has been one of the most mindblowing experiences of my life. The product is phenomenal and on a league of its owned compared to Beyond Meat. IMHO Beyond taste like cheap school lunchroom burgers and Impossible tastes like something I would be excited to feed my family. If their pork products are great then I am ALL in because Chicken products are by far the easiest thing to replicate. I'm extremely excited about this product.
- Visa
They make a ton of money on transactions. I saw them hiring for blockchain development so it leads me to believe that they're adapting.
- Square
I work in the fintech space and I like their modest approach to financial services. Their acquiring of a bank charter is actually incredibly important due to all the procurement and legal processes that go behind being a fintech company (abiding by federal security laws, etc). The one reason I like Chase banking is because I enjoy their app. I see Square as a competitor to Chase, surprisingly.
- Apple
Apple designs its products with customer service in mind. I think the future of education technology will likely go to Apple because of this. Their screens and cameras are wonderful and I can see them pioneering computer vision products because of this. They are THE American Tech company.
- TMobile
Aggressive as hell and grew to be a large player through savvy moves across time. Their customer service is a highlight for me.
- JPM
Customer service for banking is unmatched IMO. If any legacy banker will make it across changes, I believe Chase is doing what it takes to adapt and think forward.
- Planet Fitness
$10 gyms, clean, and casual enough for the general population. You can't beat $10 gym membership when you're broke as fuck. I've been a heavy lifter before and still used Planet fitness in my transitions across states and whatnot. I need to look at their numbers more closely.
- Volkwagen
I trust Europe and Japan to take EVs more seriously. I don't know who will seriously come close to competing with Tesla in the long run but they'll have to.
- Panasonic
Panasonic, much like AMD, did not immediately reflect the value of what they have produced. AMD did not explode inline with bitcoin or cheaper GPU consumption, in the same way Panasonic did not reflect a massive spike in price after speculation in Tesla grew. They're an important arm to the EV market that spreads across many players ranging from Tesla to Toyota to big tech.

- Lyft
I think Lyft's focus on customer service and regional clientele will pay off against Uber, who is growing too quickly and spreading thin. Lyft will benefit from the development of computer vision and Big tech's interest in automanufacturing.

- Crypto (Bitcoin or XRP)
I like crypto as a technology as a software engineer. I see the value in a faster process for procuring and exchanging legal tender that does not have to go through the bottleneck of the ACH process or through legal issues like the PATRIOT ACT or the Bank Secrecy Act. It still fundamentally respects those laws without the frustrations of banking service bottlenecks. I think the halvening protocol has an interesting affect on Bitcoin and supply and the market that it's trying to generate.

How long does it take for my balance to unlock?

Your balance is unlocked after 10 confirmations (which means 10 mined blocks). A block is mined approximately every two minutes on the Monero network, so that would be around 20 minutes.

How can I prove that I sent a payment?

The fastest and most direct way is by using the ExploreMonero blockchain explorer. You will need to recover the transaction key from your wallet (complete guide for GUI / CLI).

How do I buy Monero (XMR) with Bitcoin (BTC)?

There are dozens of exchanges that trade Monero against Bitcoin and other cryptocurrencies. Check out the list on CoinMarketCap and choose the option that suits you best.

How do I buy Monero (XMR) with fiat?

How can I quickly exchange my Monero (XMR) for Bitcoin (BTC)?

There are multiple ways to exchange your Monero for Bitcoin, but first of all, I'd like to remind you that if you really want to do your part for Monero, one of the simplest ways is to get in touch with your merchant/service provider and request for it to accept Monero directly as payment. Ask the service provider to visit the official website and our communication channels if he or she needs help with system integration.
That being said, the community has been recommending two services in particular, XMR.TO and MorphToken. These services are only recommendations and are operated by entities outside the control of the Monero Project. Be diligent.

How do I mine Monero? And other mining questions.

The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.

2. Wallet: CLI & GUI

Why I can't see my balance? Where is my XMR?

Before any action there are two things to check:
  1. Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
  2. Is your wallet fully synchronized? If it isn't, wait the sync to complete.
Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized.
You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait.
If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.

How do I upgrade my wallet to the newest version?

This question is beautifully answered on StackExchange.

Why does it take so long to sync the wallet [for the first time]?

You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization.
Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).

I don't want to download the blockchain, how can I skip that?

The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld.
Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy. A remote node can't see your balance and it can't spend your XMR.

How do I restore my wallet from the mnemonic seed or from the keys?

HowTo: Create and Spend a Electrum Segwit 3of3 Multisig wallet with Trezors

I wrote a simlar post in Bitcoin about creating a MS wallet without a Trezor, this guide will focus on creating a 3of3 MS wallet with three Trezor's. Hopefully it should be obvious how to extend this to N-of-M for any value of N or M. You can also use this as a blueprint to do MS with non-HW Electrum wallets like Android.
It should be noted that this is the most general case method for setting this up. This allows to replace non-HW Electrum wallets into this procedure where HW-wallets are referenced. For the far simpler method, just pick Cosign with hardware device instead of Cosign with key as I outline here. If you choose Cosign with HW you can do the entire process in one wallet file in one session.
The main advantage of multisig is that it reduces the risk of one compromised seed exposing all your funds. Although this is exceedingly complicated, the added layer of complications make it all the more difficult to compromise your funds. Most of the complexity is on the initial wallet setup. Sending is only a bit more complicated, and Receiving is the same as it would be for any electrum wallet.
We will be creating three wallets here, and each will use a Trezor with its own seed, passphrase, and public key (Zpub). If your just wanting to play with this process you could use one Trezor with three different passphrases. Electrum will treat this like three different wallets, since... well since it is. The Zpubs will be calculated by Electrum.
For all references to wallet passphrases or encryption passwords, I highly recommend you generate six-word passphrases. Three simple ways to construct a six-word passphrase would be to either use EFF diceware long wordlist to roll for 6 words, or create a short six-word BIP39 seed and use that as a passphrase, or create a random Electrum seed and use the last 6 words. You will need to take care that all six-word passphrases are equal or less than 50 characters. Longer passphrases can produce some unexpected results. Whenever you need to create a passphrase or password from here on out, create a six-word string as described above.
Assuming your have your Trezors initialized with passphrases enabled, our first order of business will be ensuring the authenticity of Electrum. For the PC's this must be done with PGP/GPG following the procedure spelled out on the Electrum website, or the secondary docs. It is absolutely critical that you are certain your using the correct ThomasV key. As of the time of this writing, the "correct" ThomasV key was:
ThomasV PGP: 6694 D8DE 7BE8 EE56 31BE D950 2BD5 824B 7F94 70E6
Once your Electrum install is validated, here is excruciating detail on creating and spending from a 3of3 multisig wallet. This assumes you have passphrases enabled on all your Trezors and that each has a unique name. For simplicity I will simply refer to their names at "trez-1", "trez-2", and "trez-3"

Three Wallet Creation passes

Do the following first for "trez-1", then for "trez-2" and finally for "trez-3". The order is VERY important:
  1. Wallet->New, name your wallet
  2. Then insert your Trezor ("trez-1", "trez-2", or "trez-3")

Receive funds into your 3of3 MS wallet

Receive just like any other wallet. All three wallets will watch the same set of addresses

Spend funds from your 3of3 MS wallet

  1. Create a TXN as you normally would on your first device
  2. In the TXN dialog hit "Preview" instead of Send
  3. In the Preview screen hit "Sign", then "Export"
  4. Copy the TXN over to your second device
  5. On your second device click Tools->Load Transaction
  6. Enter your partially signed TXN
  7. Verify the Status reads "Partially signed (1/3)"
  8. In the Preview screen hit "Sign", then "Export"
  9. Copy the TXN over to your third device
  10. On your third device click Tools->Load Transaction
  11. Enter your partially signed TXN
  12. Verify the Status reads "Partially signed (2/3)"
  13. In the Preview screen hit "Sign", then "Broadcast"

Conclusion

Certainly more complicated than a non MS wallet, but a lot more secure. Also be aware that the Segwit MS TXNs are about 40% larger than the native Segwit TXNs, so this does generate some additional cost in TXN fees.
