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.
