To avoid wasting time on bounties you need to do research, not just any kind of research but a very good research, kingcasino turned scam unexpectedly, some projects won't end well, know which one you'd use your energy on
I think bounty hunters deceived themselves for Kingcasino. From the look of things, right from the start, kingcasino looked shady. The project IEO was also done on shady exchanges. So, it was very clear that it would end up as scam project. The outcome was not surprising, but the mistake that bounty hunters made was that they followed the bounty manager or company that managed it, instead of doing their own research.
