You need to read their white paper and learn to know it from yourself if the bounty is worth it,
I mean you should learn from your self and what would happen if they gave you a bounty and it ended up being a scam you would blame them for it.
Or what would you do after the bounty ends you would start another thread to know another bounty?
You found out about this forum or at least someone told you about it so I think they should be the one you should be asking.
