In Belgium (where I live), these gains are tax free. So that is one country you could potentially move to to avoid the tax. The same applies for the UK, Malta, Cyprus (non dom regime) and Monaco. If I were you, I'd consider doing the perpetual traveler thing for a while (i.e. while having a base in Malta, which is cheap) and cash out + reinvest in stocks. After a few years, move back, and then pay capital gains tax on those future gains.
You can leave most countries without realising the capital gain, even if you've built it up within a country. This is why certain people move to a country without capital gains tax to sell their company. Obviously I don't know Finnish tax law, but within the EU it's generally the case (for now). Have it checked by a _GOOD_ tax lawyer, if that's what you want to do.
Building up capital is important - once you have it there's a lot you can do.
