Woofun AI data shows that a Bitcoin miner-stress composite has entered a zone associated with severe pressure, highlighting the divergence between efficient and inefficient fleets. Hashrate Index estimates sub-19 J/TH miners earn $81 per MWh, while 25-38 J/TH fleets generate only $43 per MWh.

Operators with older hardware or high costs face curtailment or forced BTC sales if hashprice remains in the low-$30s. This stress acts as a solvency test, where network difficulty adjustments may eventually favor survivors with lower energy costs and stronger balance sheets.
