Conmen and literal criminals only go away if you make them go away or they stop making money. There's zero way to prevent any of these boring and antiquated scams from happening, no one to run to when it does happen, and zero way to undo it by design. Crypto people approach this by denying it happens, then that it matters.
Crypto is a holy grail for scammers, fraudsters, and conmen. You can "work" marks that live in an entirely different hemisphere, with no cut taken by whoever would normally get the money to you, the market is chock full of fools, by the very nature of the complete lack of utility of crypto so it's predominantly "true believers" who are obscenely gullible, have been scammed like three times before, and still will DM random people on instagram to get "in" on "the next big thing".
Even Casinos aren't allowed to put their thumbs on the scales this overtly.
