When in fact if the bank or government that can think, definitely crypto currency can be managed in such a way, but maybe for now this still has not found the way. We'll see gold, gold is something that is obtained by way of mined like bitcoin, if gold price can be managed, why bitcoin can not.
I used to think, why every bank in this world can not provide space for crypto. If they want to think together for the development of the world, especially the economy. they should be able to synergize.
