I can say 100% that 60% of all bounty is a Scam. The reward for them is either given and the tokens will lie on your wallet forever or do not give at all. Then what's the point of doing this ?
The number of bounty campaigns seem to be increasing, but the increase does not in any way justify or bring about more rewarding and genuine bounties. Instead we keep on having those who just waste the time of bounty hunters. Well, we do not know if the next year we are about entering will bring improvement.
