I think a lot of this sentiment comes from the fact that people buy into and hype up an ecosystem that is very up-front about how much responsibility lies with the individual (all of it!) and those same people get upset when they get taken for a ride and lose their shirts.
Play with fire, get burned. If you don’t want these things to happen, stay in the regulated financial system where guard rails exist against market manipulation.
Personally, I’ve done my due diligence and decided that the crypto community is a raging dumpster fire that is speedrunning the last 200 years of centralized financial fraud and somehow failing to learn any of the lessons along the way. For that reason (and because I lack the time to exhaustively vet every project that looks interesting,) I’m staying out of it.
a.k.a. please don't feed the trolls
