I have read similar experiences with the other bounty hunters. And sorry to say that many bounties today are not the same anymore. If they pay, you should be grateful for that but if they don't then at least you have seen that coming.
my bounty experience on 2019 was not good enough because i joined a few of them got paid but it still not worth because the project never got listed into an exchange
Now the token that was paid to you became a display to your wallet. What token is that? many projects are like this when the team have gathered a decent money then they wouldn't pursue the listing to avoid dumping.
