CEX has suspended mining because the current USD/BTC price is below their minimum maintenance fees.
If BTC reaches or exceeds $366.139 (this target will increase with "btc difficulty" over time) then presumably CEX will re-activate its mining operations.
Right now you're trading non-mining GH/s based on speculation that it might be re-activated at some point in the future.
You are way better off trading UMISOO from HashNest (BITMAIN).
