The government will look for a way to regulate the blockchain industry and make use of it possibility government are already accepting crypto and we are still at the early stage of adaptation.
There is no doubt that the bank system will never be abolished as that is one way for a country to developing the economy and still able to supervise the outflow of money to make sure everything is going adequately.
If the government wants to regulate cryptocurrency in the country, it will develop a better way to collect the taxes just like in the US, although many things have to be fixed. Bitcoin and other coins that provide decentralized technology for people to manage their coins without the government recognizing, it is also not a completely wrong choice as bitcoin provides the freedom to control your funds, to transact as you want as long as you know what you are doing.
