Honestly, your best bet is to wait and hold on to it. In a few years who knows what could happen. Maybe governments will adopt it and it will become the worlds currency. At that point you won't have to sell your Bitcoin you could directly buy the goods you want with it. This way you get no CG.

I would avoid the schemes you are trying to do. They could work BUT if they find out you would be in trouble :(.

I know how you are feeling. I'm hate paying taxes. The best ways I find is to hold on to your coins (or withdraw a low amount, lower than 5 000$) OR use a bitcoin debit card.
