I highly recommend against filing capitol gains tax. For what reason is it wise to inject crypto mining with the state? They shouldn't be allowed in it, but if everyone lets them in then they'll think it's all ok until a Supreme Court case goes to show they have no right (it's only a matter of time).
Filing capital gains may protect you from future prosecution, for hiding your income. The state may be evil, but we all have to play by the current rules or be ready to face the consequences.
Uh... so you paid more taxes on actual income, and you expect them to come down on you for not paying less tax through capital gain tax?
More taxes on actual income? No - You pay the taxes which are due. Whether they are based on income or capital gains.
The state may still come after you unfairly, but at least you have done what is expected.
