The altcoin bounty hunters are passing a very hard time, no doubt. We had a very few good bounty campaigns! After Cartesi, I am still finding another good bounty to do hard.
No one is forcing anyone to join in these and there are still people looking to join all these shitty projects and promote them without even having a clue whether you are dealing with a real business or a phony looking to make quick money. If you cannot find a solution for that then there is no solution in weeding out shit bounties and projects.
