thank's for your reply.
I think genesis mining is good product but i think that the hahpower on the contract is not exactly. If you mining on GPU you have 2x 3x hashpower in most case. on genesis, the pro is the power consuming, it is included on the contract, if you mining with custom rig you have to find a place and the power. So if you love mining i think genesis is a good product. Yes the return is not very fast.
