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.
Not only online, people scam by giving people offer to double their money in real life too.
I know people in my country who come up with such business and innocent people deposit local currency with them with the hope to get it double.
Online scamming is easier because the scammer identity remains hidden.
We should avoid any such mouth watering offers and stop being greedy.
