this is the unpleasant part of being a bounty hunter, after we have spent a long time doing bounty tasks, we still have to wait for the coin to be distributed, and wait again until the coin is listed on a certain exchange, and then can sell it, but the reality is instead not all bounty coins will be listed on the exchange, I still have some bounty coins that are not listed on any exchange until now
Absolutely right, that's the tough part of being a hunter, though before we start participating with any project.
We must do deeper research and keep our self updated with how the project is working, it will avoid us to participate with scam project.
Distance yourself with any possible scammers, you can do this by taking time to review and study what are the patterns of this kind of developers.
