It is the best move by a government to not act against cryptocurrencies, but legalize and get under their control. But I have doubts, that it would be the best move for us in the result of direction by governments and the traditional finance institutes.
There's nothing that can be done about that. I'd like to have my cake and eat it too, but the fact is, cryptocurrencies can't go sky-high in value
and not be subject to regulation by various governments. There's no way around it.
In the long run, I believe that we will see legacy banks offering custodial bitcoin services. One should obviously stay away from such services, but my point is that it will take significant regulatory oversight of cryptocurrencies before legacy banks are offering these services.
