Bitcoin's July Difficulty Adjustment Offers Miners a Brief Lifeline

Bitcoin's upcoming difficulty adjustment could provide miners with a 16% relief, but it may not be enough to address the industry's underlying issues. The next adjustment is expected around July 26, which would lower mining difficulty by roughly 16%. This move would give remaining machines a larger share of the network's rewards, but it won't resolve the expensive power contracts, debt obligations, and strategic pressures pushing some major companies away from mining.

Transaction fees have provided little cushion for miners, collecting only 0.69% of block rewards in the week to July 13. Hashprice, the daily revenue miners expect from one petahash per second of computing power, stood at $30.88 per PH/s/day on July 13, with a seven-day average of $30.39. This level was at or below breakeven for many operators depending on their power costs and machine models.

CleanSpark is an example of an operator that could benefit from the difficulty relief, but it still produced only 614 BTC in June, down from 671 BTC in May. The company sold 179 BTC at spot and another 250 through call exercises at an average realized price of $69,056.

A double-digit cut would be a welcome improvement for miners, but most of the benefit would flow toward operators with the newest equipment, cheapest electricity, strongest access to capital, and balance-sheet flexibility. This could lead to a more concentrated industry, as efficient fleets switch back on, low-cost operators gain network share, and aging machines remain dark.
