guys how to get around local tax laws and convert crypto earnings into legal fiat?
If the government in your country regulates cryptocurrency then you will have no problem in changing your stock to fiat currency. all the while, if cryptocurrency is prohibited in your country, then that's the time you have to go through blockchain to change crypto to fiat for as long as you have the credit cards which accept crypto. You will have to go through some process in exchange to do that though like in coinbase.
In short, you should go to a country that is no hassle in giving you a service you want about crypto currency. You've stated a very obvious matter, of course you should only regulate your crypto in a country that allows it.
Also you should know first the security of the country for you to avoid being hacked or scammed. Security is very important when it comes to crypto currency. Most especially if it has a potential or if you're going to convert it into fiat. Fiat is more vulnerable to negative things.
