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.
If you see any program, site or person giving you X amount of money on your investments in very short time and without asking you to do any work, then for sure that is a scam. No one on earth gives you free money on investments. Also note that the returns on staking etc are only between 1-20 percent and not 2x-3x.
