Not necessarily digital. You can be a "resident" in another country while not being a citizen of that country. This might give you some tax benefits depending on the country. Usually taxes are paid based on your residency. Only a handful of countries claim taxes based on your citizenship, the US being one of those. It means US citizens can get taxed by two countries at the same time if they live abroad. So called double taxation. The best deal might be to have your residency in a country where there's "territorial taxation".

Many countries have great tax policies for bitcoiner expats, for example UAE (Dubai), Malta, Paraguay, Portugal, Germany, Malaysia, Puerto Rico, Cayman Islands, Singapore, Belarus, Switzerland, Georgia.

The best combination of countries which works for you dependends on where you come from in the first place. But it's always better to "plant the flags" early, that's true for every expat. You don't need to have your bank account(s) in the country where you're a citizen. You don't need to live in the country where you're a resident, etc.
