Well, I think crypto does solve a couple important problems faced by many speculative markets and casinos: Regulation and taxation. It's any scammer, grifter, and thief's paradise!
It's a paradise for all kinds of scum and dark people, like pedos, human traffickers, drug dealers, ransom hackers, mafias etc. And all this receives a great care from the current fascists USA government, who invested in crypto a lot, I suppose.
