I think it's far from happening since the Bitcoin is decentralized. The Government will surely not support anything that they can't control. so for that to happen, the cryptocurrency will be under the Government. this is just my point of view on this matter.
of course the government wants to use it for the prosperity of the people, so surely there will be policies that will regulate it, even though we do not know the current policy to be taken, but i think it will have many advantages for the development of BTC
