They interrupted translation bounty - this is not a good sign. Investors still prefer to read white paper in their native language, and exchanges often require white paper translated into several languages ... Silence is not always a sign of scam, but alarming
Yes, SCAM Bounty, not only translation

WingsCAM_b = BITWINGS SCAM Bounty 100% IMHO
it seems so from the start this project was suspicious, first they had MVP but with usecase that didn't make sense, second that they did IEO on p2pb2b which like bitcointalk members knew this exchange was very bad and now there was a drama of trimming bounty participants 100% chance of this bounty scam clearly exists.
Not only bounty I think the project was also a scam one because how can a phone generate 2 ETH when even a good gaming PC can't do that? It was quite strange to me from the very beginning.
