I have not yet made any changes to my business and personal tax situation, and also not looked much more into this. After researching basically every possible solution, I concluded that Bulgaria was in fact one of the better (and easiest) options for me. If the world goes back to normal sometime this summer I will most likely incorporate my company there unless I come across an even better setup/country.
Are you also looking at Bulgaria for tax residence? Is it because of crypto or your business?
