There are plenty of countries with no regulations at all so you could probably look into those.
In Romania, the tax people said they don't have a legal framework for taxing Bitcoin profits, so they don't tax them, for now at least. This is because Bitcoin is not considered a currency, financial instrument, product nor service.
However, if you use a Romanian bank account, you will be met with lots of confusion when explaining this, and might actually have to pay the 16% capital gains tax regardless.
