Every minute they’re not mining, they’re losing money in the sunk cost of (depreciating) hardware.

Which is fine because they only shut off a few hours per day and the amount they get paid to shut off is more than they would have made from mining.

Riot recognized 66mm of depreciation on only 50mm in revenue.

That's because Riot is a scam to transfer money from investors to their executives.
