IMHO this exposes risks related to the current state-of-the-art in digital currencies. BTC, and others, are really just an experiment; new technology will replace it that will be far, far more resistant to the nefarious use-cases in effect.
I can say the same thing about the US Dollar, but we still have it.
No, the current state-of-the-art in digital currencies completely changes the ballgame, relative to fiat. There's a reason BTC is the main payment mechanism for ransomware.
