According to CoinWarz, the next difficulty adjustment is expected at block 927,360, moving the target from 149 trillion to close to 150 trillion. That is a modest rise, but it matters because Bitcoin miners are already working with very thin margins. Hashpower is strong enough to push difficulty up even while returns stay near record lows.

Hashprice Sits Near Break-Even

Hashrate Index data shows hashprice is hovering around $38.3 PH/s per day, a touch up from a recent trough below $35 PH/s on November 21. Reports indicate that $40 PH/s is roughly the break-even level for many operations.

When revenue per petahash drifts under that mark, some miners face a hard choice as they usher in December: switch off rigs or keep paying to mine. Average block times have been close to the 10-minute goal, with the network recently averaging about 9.97 minutes, which helped trigger the most recent adjustment that dropped difficulty from 152.2 trillion to 149.3 trillion.
