You have said a mouthful here, @misdoma, IMHO. I feel that there is a "fight to the death" coming over "official acceptance" of cryptos in many countries, and that at the end of the day, cryptos will have indefinite longevity where there is a large set of goods and services that can be bought directly with crypto coins (i.e., people do not have to cross the crypto-to-fiat bridge). Japan is one country where this process is already advanced.
