There are many now in several countries applying to the ownership of taxes on cryptocurrencies.
Honestly, I prefer them not to be set.
but why do you want the government in your country to regulate crypto??
Adoption is one of the positive results of government intervention with crypto. But, on the other hand, that also breaks the main purpose of crypto which is decentralization.
With the government having its regulation through cryptocurrencies, the first thing that anyone can think of is all about taxes. If there's no money in it, the government won't be touching crypto. But as they all discover that there's money circulating on it and it's not just millions of dollars but billions are there and has reached a trillion market cap for its potential, they won't be stopped to regulate it.
