Well, at least in my country, cryptocurrencies are still a loophole when it comes to tax, regulations aren't thought out and cryptocurrencies aren't taxable. Honestly, the amount most of the bounty hunters earn aren't enough to tax, I mean, when it's taxed it would be so low that every user here would be forced to use multis for bounty hunting, otherwise, you can't make a living from it.
So taking bounty hunting as a freelance off-record work. Let's be honest here, some of us have switched to full-time bounty hunting from our day jobs, to be a freelance taxpayer, you need a tax registration certificate, how many of us have it here?
