It offers 2X of the amount of money you send in.
I can't believe that people fall in those scams. Have you ever seen in real life someone tell you "Transfer me some money in my bank account. I will transfer you back 2x."
Why would someone do this?
People are insane with bitcoin...
Bitcoin is not a tool to make people get rich quick. It is just a currency. It works as a currency.
I have heard very often when people say: Lend me some money to play poker, I'll win and pay you back 2x. But as a result, they always lose and they blame luck, but the most curious thing here is that they always win with last few bucks (as they state).
Problem is wish of easy money, no one wants work, are lazy for that so when someone offers such proposal, it's very hard for super lazy person to deny it or even think whether it's scam or not, they hear what they wish and then try their best to believe themselves that it is truth and it can't be scam.
I think it's seriously mental problem that people really fall in such scams.
