Bounty hunters should always be ready to be left without payment and there were many such cases in my practice. There is nothing to be done about it and it is useless to complain.
Surely the hunter has experienced it like that sometimes gets paid but there is no price at all just being trash in the wallet, the hunter must be good at choosing projects that are worth following so there is no remorse later.
There are many bounty hunter who work frantically with all the bounty they find. But this way of doing things I disagree with the loss of strength, but I am not sure to bring success
If you are already a long time this market, then you should understand that it is better to spend more time researching a project than to participate in a scam bounty
