There are a huge number of Bounty Campaign. A very large number of projects. But I like your remark very well. It's a bit of a way to get diversified until one ends up paying.
ROFLMAO... It can't get any worse than this. So you want the bounty hunters to do all these bounties, until they eventually gets paid? What if they fail to get any rewards even after doing 10 or 15 different bounties? Take my advice. Do something useful during this time, rather than chasing these bounties which never pay. There are a lot of things that the new users can do apart from bounties. The only thing is that they should be having the patience to learn new things, which can be applied later on the cryptocurrency market.
Bounties still pays and I've earned from several projects since 2018, many don't know how to do good research on projects before promoting them that's why they land in trouble after the bounty ends, the two most active ways to earn in crypto is bounties and trading
