Yeah, high reward, but also don't forget at the end of bounty you will get of this :

• Cut Reward by Developer
• Introduce KYC System went at the beginning they said we don't need to do a KYC (Classic Reason: To avoid cheating/fraud)
• Delay Payment
• Another Promise

Since the payment using a token, I'm not really surprised this it's not the first time i see a bounty with high estimation payment using a token. I have my own DD, this kind of bounty i will skip it cause the economy token prize will be destroyed with bounty hunter and just wasting my work.

Seem like you already know how to make due-diligence for some bounty. Then just use your own DD, if you feel the bounty not really realistic based on your survey/review then avoid. A good user always makes their own DD no just using a popularity BM Name, except for a bounty who just rushed went new bounty was born.
