RE:RE:RE:RE:RE:So at 9650
For sure, BTC price is volatile, for reasons I don't understand (whale owners dumping, BTC broker issues, et al).
Lowest power cost with most efficient miners appears to win the prize. China co's are biggest worldwide miners now and their coal provides cheap power, until someone (enviro) or something (Corona virus) or tech (older miners) slows them down.
HUT model (with public full disclosure) is to create state-of-the-art mining sites using Bitfury supplied data centers. Don't know what miners they are using in the BF data centers (S9 likely, S17 possible, M30 on the way). I believe BF still owns about 47% of Hut stock so both have much to win with the recent renegotiation of the "supply deal". They should both be pleased to see the SP appreciate.
The Q3 reported all-in mining costs (excl G&A) of $4363 USD points at a 50% margin business - if BTC holds near $10K USD. If greater BTC price, game even gets better.
As long as G&A is not off-scale, like this a lot.
