I have no love for Genesis and have spent a lot of time telling people "don't do it" regarding cloudmining, but it would be quite a surprise if they turned out to be a complete fake.
Do you think that cloud mining at all is not worth it? I think Hashnest mining may be profitable, because you can mine, and you can sell your mining power at some point. It's like a stock market - getting dividends and trading your shares. But in mining your dividends may be higher than 100% annual.
