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.
You won't fall for it only if you know that it is a scam because most people that are desperate and are newbie when it comes to earning money online so whenever there is someone who presents them the idea of doubling their money, they don't hesitate or doubt because they don't know that it is a scam.
