Stupid people not only exists in crypto but they exists everywhere therefore we see these scammers keep on scamming. I still see people willing to double their fiat by depositing their money to the scammers. If the whole world would become intelligent there will be no space for such scams. People are lazy and want free money, and therefore they fell in these traps.
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.
