Your original claim was that the difficulty adjustment makes mining *always* unprofitable. Whether or not a mining corporation is operating on losses at the moment is irrelevant to the fact that your claim is factually untrue. Corporations come and go and unprofitable operations will go bankrupt. The core premise that mining is always unprofitable, as you claimed, though is untrue. A difficulty adjustment of 1-5% isn't going to ruin a miner that is capable of operating with profits beyond that. The current adjustment is looking to be only +0.81%. If a miner was operating in profits this adjustment period, they're likely going to be operating in profit the next as well.
