Bitcoin hashrate set fresh records this week, underscoring rising network security and competition. According to the source, hashrate climbed to 1.12 billion TH/s on September 12, 2025, as mining difficulty reached 136.04T. The surge highlights stronger miner participation even as profitability tightens.
New highs for hashrate and difficulty
The milestone coincides with an all-time high difficulty of 136.04T. Blocks remain steady while the cost to find them rises. Projections indicate another difficulty adjustment on September 18, 2025, with estimates of a 6.38% increase to 144.72T, suggesting more pressure on margins.
However, the Bitcoin hashrate boom does not mean fatter miner wallets. Hashprice has fallen 8.39% to roughly $53.10 per day per PH/s, according to the source. Growing competition from AI workloads for mining infrastructure is cited as a partial driver, potentially redirecting energy and hardware.
Miner margins face headwinds
Miners must balance higher difficulty with falling revenue per unit of hash. This may accelerate upgrades to more efficient rigs and smarter power strategies, and spur relocations to cheaper energy hubs.
Key points:
- Hashrate reached 1.12 billion TH/s on September 12, 2025.
- Difficulty hit an all-time high at 136.04T.
- Hashprice dropped 8.39% to about $53.10 per day per PH/s.
- Next difficulty adjustment projected for September 18, 2025, up 6.38% to 144.72T.
