that will make you 32 per month at the current DIFF bitcoin value Rate not factoring that in.
It will take you 5 Months to ROI on your investment which I fell is a big rip off scam !!!!
USD only
According to your calculations (which I presume you have done) if you were to buy your own hardware, pay your own electricity and mine in the pool of your choice, how soon will you ROI?
I don't pay for electricity I get it free and Have three antminer S5 running at 1200 GH/s that's 3.6 TH/s at default speed NO OC. And Don't have to pay to renew every 12 months! I still think its a scam!
Free electricity is awesome! Good luck dude! But yeah, some (most) people don't have that privilege. I personally don't have the living condition at this time to even run a miner - so cloud mining is the only way I can operate. I lucked out getting a contract when they we still offering 5 year contacts, so I think I got the best option that there can be for cloud mining. That will hold me over until my living conditions change and I can mine again.
So the short answer, is no, it is not a scam. For some people it happens to be the only option out there.
