Why are you limiting yourself on Europe?
There are countless offshore Banks where you can deposit up to 200k without having to care about taxes and such.
The thing is, if you want to use your profits to invest in something else then yeah you really have to get them taxed
so you can justify their existence. If you're looking that way, a "fundraising via bitcoin" would be a nice option if you
know what I mean, from there and on I don't think you're going to get taxed for your active capital.
Thanks man, this is something that I can think of. It means I can spent on my personal expenses, like travelling, pay rent, buy food etc. Do I understood it right?
The Isle of Man has not capital gains tax but its rather cold

I do not want be resident of the country

I was doing a similar research an year ago.
Cheapest EU country just for Profit Taxes is Bulgaria. There you are paying just 10% as taxes. But still the money remain company's money. If you want it clean for you, you need to pay 5%-15% dividend taxes. In Bulogaria you need to pay and monthly ~80 social taxes. It's mandatory.
Another good options are Malta and Croatia. For example in Croatia you could have a company and you are not obligated to pay yourself a salary (taxes respectfully).
when talking about bitcoin profit taxes, which is usually paid by private people, not companies, it might be better to look for a country where there is no tax on bitcoin profits at all.
I heard Denmark has no tax on it and Netherlands only 5%.
But I can not confirm this, only rumors.
I am not planning to become a resident just because of bitcoin, I plan to get tax certificate.
