this seems like a massive hack, it looks like a show of power from the hackers. They could have done a lot of bad with this hack., they went for money, but realistically they could have made a stock market crash if they timed this shit properly, bit scary to think about.
I have seen many times every time Elon Musk tweets, below in the comment replies is just a bucnh of bitcoin scams. It was the same scam you could see for months under Trump´stwitter comments, every reply was that Dr whatever and then some bitcoin scammers pretending to be Elon tweeting. I reported it at least 20 times and i saw it happen for over a month,. every single tweet from trump and elon were being targeted. I suspect the people behind that scam are probably related to this one too. The writting of the scam tweets is very similar too.

They also hacked Biden´s account, thats gonna be super embarrassing for all the idiots who actually saw his tweet and send "Biden" bitcoins. Those ppl maybe deserve it for being idiots, who fuck would "send Bitcoins" to Joe Biden and expect the double of your money :D??

weird shit all this hack , i am sure it will be chinese origin.
