Well, where to live is also a personal preference thing, not just a tax issue. Not knowing your preferences, for someone into crypto Ill just list the usual european countries: Cyprus, Malta, Portugal, Switzerland, Bulgaria.
And then Ireland is ok for having a business, but not great for individual hodlers. Czech Republic is ok for hodlers (no cgt if held >3 years), so so for a business. Germany is good for hodlers (no cgt if held >1 years) but bad in all other aspects.
France and Spain are to be avoided entirely.
But also, you dont have to stick to one country. If you mix︀ countries, and split the year between multiple countries, suddenly a lot more is possible.
Also, why limit yourself to Europe? Lots of other great places to live around the world︁ that also have reasonable or zero taxes.
