i think the government want to control everything in their country ...
by legallysm and some of them think about their country's own currency ..( if the crypto affect on their currency )..
and the government want to handle all the currencies ... that's also for caring of people and avoid frauds ..!!
but the crypto standing on trust !..many advantages and disadvantages are also in crypto ...but more people using this currency possitively !!
crypto is a good plattform for the investors , business companies ...i hope government can understand this and approve the crypto...
