Critics are unmoored? This technology is inevitable?

I don't believe that's true. It seems to me that it might find a niche in the corner of the Internet and eventually be forgotten by all but the most ardent followers.

Many countries are banning cryptocurrencies for many of the reasons critics have been rightfully skeptical. I can't imagine why that trend will stop.
