There are many people who have been scammed this last year with the livestreams that they made on YouTube with hacked channels, but really if you think about it, nobody is going to multiply x2 the btc that you send to the wallet that they indicate.
It is really shocking to see these kind of people who believes in such frauds very easily. It is a very poor tactic that you think of making people believe you by verified accounts. You just directly want their crypto from people to double it etc. and you are proving it clearly that it is fake. I really don't understand how foolish you should be to believe such thing.
