Unless the price of BTC follows suit. But it is not happening at the moment. I am unsure if HF has a clause which terminates contract. I am currently at a zen mode when it comes to ROI. I'm happy each day as long as the contract is running (i.e: The return is higher than the daily fees)
For now you have a positive return but think about bitcoin halving. If USD/BTC will not be better like 600-800$ / 1 BTC you will end in a negative return. I estimate that in less than 6 months your contract will be canceled due to negative payout. If you speculate about growing value of BTC, you will make more money buying coins now, and wait, then buying mining contracts, but I don't think this will happen. Who knows...
