I have not cashed out my crypto yet and still thinking about Germany. There are some things that I do not like here. Like I can only register a lease but not get a real 'proof of address' for tax purposes like in other countries. Tax legislation is also much weaker than in other countries, especially when it comes to international taxation. No clear rules on what is habitual abode or permanent home etc while Germany clearly states that.
I have talked with lawyers in my home country that says that I do not need all this stuff. Some countries do not even have a registry of where people live, I think Australia is one of them. However, it makes me much more uncomfortable that I have to rely on a lease written between 2 people. Bank statement adds to it, but even the tax residency
certificate you get in Georgia doesn't mention what basis you got it on nor that it is in accordance with a specific tax treaty of country X. The really wealthy that want to sleep good at night are not in this country
