when it was still of little value and no one was interested, let alone seeing it firsthand, because it was considered a waste of time doing anything related to bitcoin. but all that is no longer the case nowadays, all are starting to look for profits from the existence of bitcoin and pay attention and can participate in it to be able to enjoy the improvements that are now happening.
actually it is only natural that the government will take tax from the profits we get as long as we make transactions with bitcoin, and most importantly there are regulations that have been made to regulate all of that. but it is rather difficult if there is no good intention from the user to pay, the government could determine certain institutions to be ratified as tax revenue regulations by giving complete permission that every exchange is only through the institution and is directly taxed when every transaction.
I believe these huge corporations starting to buy billions of dollars worth of bitcoin made this a situation. I mean governments had to do something about it because these companies were pouring money into it like crazy and there had to be laws. What happens when you put in 1 billion dollars and it becomes 5! That is not like me putting in 1k and getting out 5k that would not matter to government it is too small, they wouldn't care about it but when a company does it with one billion that becomes a huge tax to care for, I mean just taxing the profit of 4 billion at a 25% rate would mean 1 billion dollars in a nations vault, that is a huge deal.
This is why I believe governments started only after they realized there was a huge amount of money to be made from it, a combined 10 + billion in taxes is quite possible in a nation like USA for example when bitcoin goes up.
True, however this is what governments do not understand, if they begin to pass laws that tax the gains in fiat once companies sell their bitcoin then do you know what it is going to happen? Those companies are going to become the biggest holders of bitcoin around the world.
After all you cannot tax gains until those companies sell their bitcoin which means that most of those companies will just refuse to do it, this already happens in the stock market as well in which many executives refuse to take bonuses on cash since they can be taxed on it and instead take stocks, so I think something similar is going to happen here.
