Your web site says that you will host my miner for 70% of it's BTC production. If you host an Antminer S4 it will produce 0.0015 BTC per day so you would take 0.00105 leaving me with 0.00045 BTC per day with no other cost to me? Am I correctly understanding your offer?
Seems like so.
And the funny thing is that even if it was true (which will definitely won't be), you would never reach ROI with such profits.
Considering the usual difficulty increase of course.
And obviously they would likely run away with your money.
Seems like a ponzi for me.
