Have you tried to do some calculations on that LEDU signature campaign allocation?? It's very little that many bounty hunters are pissed off about it, please try doing your own research first, the whole pool is like 700$ 😣😣
OP is talking about safe not if they are worth joining. Its a lot better than many other bounties where participants were scammed, and also this is stakes based, so you can not tell how much one is going to receive. As of now, there are few participants, you may be able to earn more than 50$ in a month. And also you can not tell if the token price increases meanwhile than the token worth will also increases.
