100% of Crypto "investors" are speculators looking for a quick buck by investing in a system that is pumping needlessly huge amount of carbon into the atmosphere. They're not well-meaning victims who stumbled into the bad part of town, they are greedy thoughtless people in search of free money.
They may be in search of outsized returns, but I think people can absolutely be victims of the ‘have fun staying poor’ meme. The implication is that if you don’t buy into crypto your assets will be decimated by inflation. I think it’s reasonable to consider that it’s not ‘greed’ but rather fear of being left behind that is driving many victims.
