But unfortunately, many project if not failed, they just give promises to the hunters to pay for their hard works after a couple of months which is still good to the part of the hunters and can do nothing but wait for the exact date that the project has promised.
When I was active in bounty campaign I have a lot of campaigns that took months before they send my stake and majority of them ended up as shitcoin this is the harsh reality of doing bounty, many bounty hunters are doing a lot of bounty on as many projects as they can, hoping that one or two of these projects will end up good in the market and they will be compensated for all their hard works.
This is why joining a bitcoin-paying campaign, whether low paying, is still better than most of these token-paying campaigns. At least, if you are in btc-paying campaign, you know you'll get paid, whereas, most of these token campaigns have no assurance that they will ever credit your share or even hit in exchanges. This is really the risk a bounty hunter is subjected to. If he is willing to wait and handle the risk, then he can go with these bounty campaigns, otherwise, stick to the campaigns that are for sure will pay the promoters. Remember to check also the reputation of the bounty manager.
