What Is Double Spend Problem? - Bitcoinik

IsitBullshit: those youtube live streams where you can send them Bitcoin and they send you back double whatever they sent

There's currently (as of 4pm Pacific time us July 12) a live stream of the winklevoss twins pushing a new cryptocurrency trading platform and when you click on it to watch and in the video it shows a Bitcoin wallet address and says that if you send Bitcoin they'll send back double whatever you send to your wall.
Eg
.1 Bitcoin and you receive .2 Bitcoin .5 Bitcoin and you receive 1 Bitcoin 10 Bitcoin and you receive 20
Is this legit? I saw one a month or two ago with Elon musk where it was the same thing. I don't think it would be worth a billionaire's time to scam people out of a couple thousand dollars worth of Bitcoin but that it the same time it seems too good to be true. Like free money.
What's the deal?

Someone hacked a shit ton of twitter accounts and posted a bitcoin address asking people to send to get double that bitcoin

Who ever did it hacked loads of verified twitters and posted a message asking people to send bitcoin to a specific address, and that who ever did, would get sent back double that amount. And loads of people fell for it. The hackers have made around $10 million so far lmao

@CBCNews: When a scammer slid into Ben Perrin’s Instagram dm’s, offering to double his investment if he'd just send thousands of dollars worth of bitcoin, he decided to have some fun. https://t.co/LdPWZP0GSf

A brilliant guy like you know that this is a bech32 because it starts with bc1 and has an x in it. So that checks out.

Coinbase: We found your ID, but your address may be wrong. Please double check it. will send one dollar worth of bitcoin if anyone can resolve this problem!!! (Just leave your address in the description)

I'm so frustrated with coinbase and their customer service. A while back ago, I submitted my ID to coinbase and it got verified. However, on the application part when I try to verify my identity I get the message, "We found your ID, but your address may be wrong. Please double check it". My address is 7056 1/2 xxxxxx, I've tried countless variations and still can't manage to verify my identity. I believe it might be the 1/2 that leads to the error. Does anyone know another way to write the 1/2 on coinbase. I've contacted coinbase support who said they would look into it, but I've been waiting for about 3 weeks and still no response on how to fix my issue. If anyone has experienced this issue and has gotten it resolved, please let me know. It will be greatly appreciated. Thank you for your time.

The Twitter hack was the biggest media hijack of all time and it makes no sense

The (alleged) story so far: Some scammer(s) paid off a Twitter employee to give them access to their admin tools and took over the accounts of Joe Biden, Barack Obama, Elon Musk, Kanye West etc. just to use them for a simple Bitcoin scam that netted them some $120K.
Why that's ridiculous: The hackers got full access to the accounts of many of the most powerful people in the world. To have that level of access in the 1980s they would have had to hijack the broadcasts of several national TV networks for 5 minutes AND have the capability to create content that would have been impossible to separate from the normal scheduled programming.
The 80s equivalent of this scam would have been broadcasting a low-rent infomercial urging people to send a check or money order to a P.O. box with a return envelope to receive double the amount back.
With such access one could either make a fortune, or fuck with the US in a way that's never seen before.
The conspiracy part: The access they had to Twitter would have been worth magnitudes more than what they made. That's why it makes no sense to waste it on a small time hustle.
So, my theories from the least likely to the most likely are:

Double-spending is the result of successfully spending some money more than once. Bitcoin users protect themselves from double spending fraud by waiting for confirmations when receiving payments on the blockchain, the transactions become more irreversible as the number of confirmations rises. Double-spending problem is the successful use of the same funds twice. Double-spending of Bitcoin is not possible as Bitcoin is protected against a double-spending problem thanks to each transaction which is added to the blockchain being verified, and the majority of funds contained in this transaction cannot have been previously spent.. Double-spending is a potential flaw in a digital cash Bitcoin manages the double spending problem by implementing a confirmation mechanism and maintaining a universal ledger (called “blockchain”), similar to the traditional cash monetary system.. Bitcoin’s blockchain maintains a chronologically-ordered, time-stamped transaction ledger from the very start of its operation in 2009. 3. RBF – “Legit” Double Spending. One form of “legit” double spending is Replace By Fee or RBF for short. RBF is a function embedded in certain Bitcoin wallets (e.g. Electrum) that allows you to rebroadcast a transaction that is still unconfirmed, in order to get it confirmed faster.. In some cases, Bitcoin transactions are sent with a network fee that is too small to incentivize A double spend is an attack where the given set of coins is spent in more than one transaction. There are a couple main ways to perform a double spend: Send two conflicting transactions in rapid succession into the Bitcoin network. This is called a race attack.
