Cryptocurrency was designed to be resistant to law enforcement and allow money to be transferred irrevocably to opaque pseudonyms, and to prevent blacklisting by any central agency. Once fraud happens, you've irrevocably lost the money.
This is a hilariously uninformed statement.
Which cryptocurrency?
I'd even argue that the juggernaut BTC was _designed_ to be trackable, and as the recent history shows, law enforcement successfully and multiple times did exactly that when needed - tracked, identified and penalized bad actors.
