Government are in any ways really scary because they can do what they want and considering that they could not get anything from people's crypto earnings through taxes because cryptocurrencies are mostly decentralized, then they will just ban cryptos rather than seeing some people who are becoming wealthy because of cryptos.
goverment actually want to control this market.by controlling it they able to track amount of money that circulate in crypto.if they know this data in exchange they can easily attract taxes from us.
