new projects making bounties on bitcointalk now are hardly successful, unlike back in 2017 when bitcointalk was the home of crypto, a lot of people were getting news and jumping on new projects from here, but now, most successful projects don't need any promotions on bitcointalk, so mostly projects on bitcointalk are "bad" with no backers, which of course gets very low value for their token and bounty participants will end up with almost nothing, i think bitcointalk bounties are done, except if they paid in stable coins are other coins like bitcoin, at least you know what you're getting.
Some of what you say is true because in 2017 there were so many people who earned through Bounty, but for now it doesn't mean that Bounty in Bitcointalk is finished because the payout is small.
Because the number of participants who enter a bounty can also affect the income of a bounty participant, especially if the amount of allocation for the bounty is not so much and the manager does not make restrictions on participants who want to join the bounty, obviously the results will be very small even though other influences such as the price of tokens in the market can also be a special reason.
