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?
Actually in my place there is no tax should be paid for bounty hunter since there is not administration for this and its true that the hunter now is different with before and its not enough income for tax. As we know we dont have any exact income as bounty hunter so how it can be taxed? And i do this as a job not hobby.
