I Notice that most projects that conducted bounty finds it difficult to enter the crypto market especially a quality market. i think most are afraid of been dump.
what are the possible reasons why tokens takes too much time before getting listed on exchange.
If you want to keep promoting new projects you have to get used to delays, I've promoted some since 2019 and only one project sent out the tokens and I was able to sell for good price, I still have like 5 projects that haven't pay hunters till today
I think if many bounty campaigns have been completed but still haven't paid the bounty hunters, then you don't need to promote their projects anymore because sometimes they scam and will harm you.
as much as possible you try to contact the bounty manager and if indeed they don't make payments then you can try to make a scam report on the reputation thread.
