If the state doesn’t know I’m in the signature campaign, doesn’t know my identity and BTC address, and I’m not so stupid as to use a centralized crypto exchange that requires KYC, should I care about taxes at all? Especially when it comes to some small amounts that most campaign participants earn these days.

For example, I would have to pay a tax on other income, which is about 20%, and those who are not employed should pay all possible contributions that are otherwise paid by the employer (pension, health insurance ...), which means about 40%+. The absurdity of the whole procedure is that the tax return should be done after each payment, which means that I should visit the tax office every week and fill out a pile of paperwork.
