Here's something to think about.... on March 26 I mentioned Dogecoin first it was down at .052 cent a coin.Today it's pushing .32 cent a coin.Bob A could have been a millionaire....Probably..
To take money out you need to convert it to real currency which kinda defeats the purpose of crypto.
I think someone designed a crypto coin and called it Pyramid or something after the pyramid scheme and people still bought it.It even has a pyramid on the picture.People still bought it.
