i already ask to chatgpt about what happend if you live 4 / 4 / 4 months in 3 country, he tell me you need to choose a country that will be your tax residency ( and it should be the one where you have more of your time and habit ), otherwise each country can claim you as tax resident. ( so it is better to clear it yourself ). Wrong ?! i was thinking about doing it, but it is already not easy to be tax resident in thailand with european banking/broker, so try to be tax resident of nowhere look even more difficult ^^.
