Gambling. Crypto is globalized gambling. It's a money laundering vector, for sure, but for the same reasons crypto competes poorly in the transaction market it's close to a last resort for high-volume launderers.
Completely and utterly unlike and in no way whatsoever similar, at all, to stock markets, futures exchanges, CFDs, options, CDOs, etc, etc, etc.
Crypto is just a speculative digital asset. Sure it's been a playground for all kinds of scams and charlatanry, because there's no oversight, just as stock markets once were (and still can be in some areas eg pink sheets), but crypto is not a scam in itself.
Notably unregulated gambling available without oversight and also readily available to addicts and children. Helpful in smashing down that redundant bureaucratic red tape the gambling industry so desperately is in need of at the small price of destroying, debilitating or general increase in suffering in peoples lives.
