Be careful which bounty projects you promoting, we start blaming projects once they turn scam for not paying us but we helped them scam many investors of their money, remember, the more we helping scam project the more crypto will get bad names, investors who don't know anything about crypto but took the risk anyways and end up losing his or her money will no doubt says crypto is scam....
Firstly, i want you to understand that it not every project that didnt pay their bounty participant end up scamming their investors. However, there's no way we can stop scammers cause they will always figure out another strategy and the best thing bounty hunters ought to do is doing research about project (which what i always do) before partcipant in their bounty.
