If somebody thinks that it's OK to give something back to their country, they are free to make a donation to the Treasury and support the government. But this has nothing to do with supporting coercion of other people to pay for stuff that you feel good about. Because there is no difference between taxes and robbery.

And since we see bitcoin as a currency (even if the government still doesn't recognizes it as such), do you agree to pay taxes because your dollars are now worth more than they used to do a few years back? (Actually the dollar is worth less every year, his value dropping each and every year because of inflation).

So Hell no, I don't think you should pay taxes for you crypto gains.
