Currently countries do not have protection for buying and selling with bitcoin. We can only agree to a 2-party transaction.
But we still have to follow the proof of purchase in this country
Pay taxes in the currency there.
I am telling you about a country where you can do anything with Bitcoin. El Salvador is the first country to fully legalize Bitcoin in its own country, allowing you to make any Bitcoin transaction in that country. Not only transactions, but all the things you used to do with dollars or other currencies, you can do those things with Bitcoin in that country. That is, if you want to pay your coffee bill in Bitcoin, you can pay the coffee bill in Bitcoin. Or if your car runs out of gas, you can pay for gas in your car with bitcoins. That means you will get all the benefits of Bitcoin in El Salvador.
