LOL! Someone definitely made a profit during the outage. In a 30 minute period, 350TH was bought on the market, bringing the price back up to 8400.

The good news for now is that 4 days from now the difficulty is expected to drop by about 7%, which will likely decrease the maintenance cost for some time. (source: https://bitcoinwisdom.com/bitcoin/difficulty). Also, when the S9 hits the market, I think people want to get rid of their S7 in favour of the S9, so I believe the S7 is going to be cheap as hell while still proftiable to use. I bought my lot around 8400, if I can sell it for 9000 before then, I'll do it, otherwise I'll just hang on to it until it goes out of profit.

The bad news obviously is that due to the diff decrease, S7 will be even slightly more successful, which may postpone the S9 getting introduced in Hashnest even further.

Your analysis is about right. The only wrong from my point of view in this equation is buying hashes which are 74% efficient.

To be honest I sold all of mine at 85 price, because for ~2 weeks I've got only 0.2BTC while hash price dropped from 100 to 85.

So I recommend you to do the same - selling today will save your investment
