Bitforx is my most favorite Cloud mining service provider. To be honest I have tried Genesis and Hashflare as well, they are legit, but a fat chance of getting your questions answered by their Customer Service representatives.

I have been communicating with bitforx's community manager, their PR manager and customer service reps for a long time now. I had to be sure I wasn't getting involved in something I didn't want to be involved. I had to trust them before starting mining and believe me they are legit, true and honest company. Their customer service is 100% perfect! And their wallet is great to use as well, everything in one platform!

also they just added Litecoin mining and their prices are the lowest in the whole market! I started mining btc with them and now i think i ill most probably start ltc mining too - not sure yet tho.
