Cryptocurrency is famous for its decentalization, i don't think it should be centralized someday. If yes, it will soon be destroyed because it threat fiat currency
The reason why people like the decentralized currency is because of the full control they enjoy over their assets. This is very important for them to make decisions according to their own thinking. Government rather is a bit tough on the other side with interest in its own interest and imposing regulation that has reduced the demand for the cryptocurrency immensely.
I of course believe in the decentralization but the economy does not flourish with this and that is the reason why the economy is passing through a bad time
