If you have income,you have to pay taxes.It doesn't matter if your income is in cryptocurrencies or fiat.That's a big part going business or trading.I prefer Bitcoin to be legalized and have taxes rather than being completely banned in the western world.It looks that more countries will become somewhat crypto-friendly,but with all the negative parts- KYC,taxes,etc. which is unavoidable,if we want mass cryptocurrency adoption we have to handle the "not so pleasant" regulations.I hope that all the good news will help for a massive price growth,when the markets return on the bullish trend.
