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.
This project does have some suspicious things, in addition to what has been said (distribution of gifts that has been delayed and unclear, IEO is in bad exchange, products that are less convincing), even the sale of Bitwing tokens is still ongoing. other than, they are brave guaranteeing that the price of BWN tokens doesn't fall below $ 0.2 USD, I don't understand how they can keep the price of BWN tokens on the market, while their tokens have not been responded well by the market and so far I haven't heard of a new partnership.
