Some countries usually use some method to extract money from their citizens who are into crypto, I think this is happening in every country that accept crypto transaction they usually call a tax payment, however they charge that some countries are taking is too much and it has made a lot of people stop investing in crypto, however one can still use P2P to purchase crypto and then hold when you want to sell you also use P2P to do that, I don't think any government can frustrate their citizen to invest in cryptocurrency because they are always a way out.
There was a time the government of my country where truly against cryptocurrency they were even arresting people that where involved in cryptocurrency it was a ban in my country but people still find way to invest in cryptocurrency and when the government notice they can't stop it they decided to accept it and then make some laws that will govern crypto.
