-Georgia : could be 0% on crypto trading, but not that clear and there is some retroactive risk, but it's clearly not 0% on traditional markets trading but it's way way worst than 10% so not a good option imo (stocks, cfd, futures, etc),
A natural person is not taxed on selling foreign stocks (unless the company has assets of immovable property located in Georgia). The gains are considered to be outside the territory of Georgia. This is probably relevant to the motivation behind Public Decision 201 on crypto income.
Georgia doesn't have a differentiation between income and capital gains in the tax code. So for now, the assumption by most folk is that trading at any frequency is just generating tax exempt offshore income.
I agree with you completely about retroactive risk. The attitude of foreign crypto traders tends to be "wow this is great. if the law changes or the Revenue Service issue a new Public Decision with a 'badges of trade' rule then i'll just get a ticket on the next flight out".
