Bitcoin mining difficulty rises to 148 trillion as miner revenue hits three-month low

TradingGain Newsroom·1h ago·30 Oct 2026, 11:50 UTC

Bitcoin mining difficulty has risen to 148 trillion, while miner revenues have dropped to their lowest level in three months. A snapshot from October 30 shows that a 25 J/TH mining rig could cover power costs of about 5.45 cents per kWh, assuming a 2% pool fee. For traders, weaker miner revenue can point to tighter profit margins across the mining sector.

Why it matters

• Mining difficulty has climbed to 148 trillion, which makes mining harder.
• Miner revenues fell to three-month lows, pressuring profit margins.
• On October 30, a 25 J/TH rig covered power costs of about 5.45 cents per kWh.

What to watch next

Watch whether miner revenues recover from their three-month low or keep falling, and how difficulty responds.
