I don´t think so, you can actually make your life of crypto. Not that I am trying to do so at all, but I think that someone that has good knowledge could do it and succeed.
Not just knowledge of course. They also need a goodand diverse crypto-porfolio or any coins in store because not everyday is Christmas, meaning not everyday is a good day for crypto. We have blood bath, too.
In any case, a bounty hunter doesn't earn daily so thatnisnout of the equatuon, mining is good source of income daily, but it requires mining rigs and twchnical knowledfe, plus, not totally cool when market is low. Then trading, which you can earn from everyday, taking into consideration that one has a skill, knowledge and good investments or coins. With these, you can survive without having regular job.
