Some people have been bounty hunters for a long time (e.g, for the past 2 or3 years) and till now, they are still on the act of hunting for more altcoins.
It is true that the reward hunters now get is so small compared to what was obtainable 2 to 3 years ago and not only that, it now takes more time to be paid than it was. So, instead of complaining, why not through some of the experience you have got, since your sojourn in the crypto space, explore other means through which you can earn more and fill your portfolio.
N.B:
This might be like a vital information. There are lots of projects that did bounty campaigns (although not all), which have decided to extent the time of payment of tokens to their bounty participants. Whose tokens are growing tremendously after listing on exchange. Which means that traders and investors of projects like these get their profits before bounty hunters are paid.
DISCLAIMER:: Although, this is not an investment advice, but an observation, which i have decided to call your attention to.
That's one of the reasons why bounty hunting for crowdfunding is in the sorry state, they are abusing bounty hunters, some developers are also locking bounty hunters token and will only be released it after investors and the developers made a profit, bounty hunters are left with crumps or leftover from profit.
The dishonest decisions by the teams kill the potential return of the bounty campaigns from my experience. The lock period is there for a reason, the longer the bounty hunters hold the bounty tokens, the better the price will be available for the real investors. The faith of bounty hunters depends on the market conditions and teams don't care about the bounty distribution.
