Even i was working bounty and i have beeb got many death coin where they have no value. Keep in mind that you will hold 50 shitcoins and it is uncertain if they can give you a profit in the future.
Many communities as bounty hunters have long lists for shitcoins, I'm sure many bounty hunters don't analyze projects from bounty so they join all new bounty, but in the end they just collect shitcoin list which has no value, so for investment and bounty hunter too analysis is needed so as not to waste time and investment.
I myself have more than 250 shitcoin tokens as a bounty hunter and the remaining 70% is from airdrops....
basically some tokens become worthless because the project is not successful and some are left behind in contrast to airdrops with an easy job we never do research first so the result is a pile of garbage scattered in the wallet
