I'm guessing your 8 weeks of 'work' was posting on Facebook or Twitter? Not really a time consuming task to do, but I get the disappointment with the final amount. Unfortunately that seems to be the way most bounties are going now, nothing like the 2017 jackpots. What to do, that's the risk you take when participating. Most bounties distribute their tokens as bounty rewards; and as some has already mentioned, the ones that offer BTC/ETH are generally much lower rewards. Might as well hold on to them and see if you can get a better return, you're not going to lose any sleep if the $8 turns to nothing.
