I will say government never want anything that can't be control by them to exist , especially when it comes to money making and freedom from tax and all laws that has to do in favour of their cabinet, and this are some reason they will never want to comply with crypto as it is decentralized and can't be control by them and also it has create freedom to so many people and making people to be rich with no hustle or has to go through a process laid down by government but some see government see crypto as a way of new life and are embracing it why some are still thinking which step to take .
Cryptocurrencies are undercutting the monopoly of governments to provide monetary policy. This is unlikely to please for example the President or the leadership of central banks. However at the same time the government is trying to keep cryptocurrencies in sight and under control.
