I just know the two, crypto miner and crypto trader. But as a crypto enthusiast, i just wanna add on we can earn money in cryptocurrency. Bounty hunting can make money from crypto currency. Just by joing such campaigns: multimedia campaign (fb, twittet, instagram), youtube campaign, translation campaign, blogs, and even signature campaign.
bounty hunting are not making much this day. it use to be lucrative when ICO emerges all around places like mushroom.
