To be fair saying crypto is the currency of pedos is like castigating dollars for being the currency of the pedos. By the same logic we could condemn about anything. Crypto by volume is used way more by scammers than pedos anyway. 40 billion just in romance scams out of SE Asia run by Chinese Gangs with forced labor that is mostly run through crypto I presume.
But that doesn't mean crypto should be illegalized for that alone either. The governments will always use those examples to lock everything down under their control and the consequences of that are far worse than the free wheeling problems that came before.
