The difference crypto has is that magic aura of infinite gains that nothing else has. Also internet anonymity and irreversibility are a beautiful gift to the scammy.
We see the same here every day but it just doesn't seem to cross many a mind.
If a bloke walked up to you in the street with a bag on his head and asked for 500 dollars cash and promised 1000 tomorrow but left no way of contacting him would you do it? Almost no one would. Yet they do it in droves in cryptoland. I do not understand why.
The problem here in crypto is that you would find a nice website and presentation that will make you think that every thing is legal and we can make millions by investing a little. As in the example, the scammer impersonate to be a coinbase site, so many will just invest in it blindly as they will think it is the real coinbase offer.
