As you are mining SHA-256, hope you are aware that by Jan 1st 2019, your hashflare account should generate 0.036BTC in profit to break even. Anything less than 0.036 BTC is going to be a loss as directly buying bitcoin and holding it for an year would have been more profitable.
This value remains the same and does not matter what bitcoin price is.
As of right now... it's something I wish i never entered into.
