Bitcoin difficulty estimated to drop 6.99%... If S19 electricity costs 5 cents, revenue falls short

Bitcoin’s mining difficulty is estimated to fall 6.99% around the 13th, according to Hashrate Index, with hashprice at $32.18 per PH/s per day. Even with that adjustment, older Antminer S19 models would fail to cover equipment power costs at an assumed electricity rate of $0.05 per kWh, a benchmark used to compare rig economics. The estimate compares with a prior weekly report projecting a 6.5% difficulty decline and $31.89 per PH/s hashprice. The data matters because it signals how much relief a difficulty drop would give marginal miners, and whether older fleets can stay profitable. Next, watch the actual difficulty adjustment around the 13th and whether hashprice holds near current levels.
