You forgot Portugal. Portugal does not tax personal crypto income at all unless it is someone's main source of income. Out of the normal European countries, Portugal is probably the best possible country to live in for a someone who earns supplementary income from crypto.

Andorra is a tax haven in the Pyrenees between France and Spain that does not tax capital gains at all and that only levies income taxes at a rate up to 10%.

If you're a crypto whale, you may want to settle in Monaco.

Outside of Europe, the Cayman Islands along with a few other Caribbean island countries, is a tax haven. The Cayman Islands have no taxes whatsoever.
