Portugal and Spain offer a digital nomad visa, if you can work remote. After a number of years, and other factors, you could apply for citizenship.

Countries that I know some of them ended up in are Germany, Portugal, and Poland. I have no recommendations myself though. I live in the States and don't plan on moving.
