Bitcoin Mining Difficulty Drops by Most Since 2021 as Miners Capitulate

Why It Matters

The difficulty cut temporarily eases profitability pressure for remaining miners, but signals broader market capitulation that could reshape Bitcoin’s security and accelerate the sector’s pivot to AI‑related workloads.

Key Takeaways

• Difficulty fell 11%, biggest drop since 2021.
• Bitcoin price halved from $126k to $69k.
• Miner revenue per TH dropped from $70 to $35.
• Winter storms forced curtailments, cutting output 60%.
• Some miners shifting to AI data‑center workloads.

Pulse Analysis

The Bitcoin network automatically recalibrates its mining difficulty roughly every two weeks to preserve a ten‑minute block interval. On Feb 9, 2026 the metric slipped from 141.6 trillion to 125.86 trillion, an 11 percent decline—the steepest since the 2021 Chinese crackdown. The adjustment mirrors a sharp contraction in global hashrate, driven by a 45 percent slide in Bitcoin’s price from its October 2025 peak of $126,000 to just under $70,000. Lower prices eroded profit margins, prompting many operators to power down older, inefficient rigs.

Beyond price pressure, miners faced operational headwinds from soaring electricity costs and extreme winter storms that crippled power grids in Texas and other states. Grid operators issued curtailment orders, forcing public mining farms to slash output, with some reporting daily Bitcoin production drops exceeding 60 percent. The squeeze accelerated a strategic pivot toward artificial‑intelligence workloads, where megacap tech firms offer long‑term, subsidized contracts. Bitfarms, for example, announced it would abandon pure Bitcoin mining to develop high‑performance computing data centers, signaling a broader industry migration toward more predictable revenue streams.

The difficulty cut offers a short‑term reprieve for miners that stay online, as reduced competition can lift per‑hash profitability. However, a sustained drop in hashrate raises concerns about network security and may pressure transaction fees upward. Historically, sharp difficulty declines have preceded market capitulation followed by price stabilization or modest rebounds, as miners liquidate newly minted coins to cover costs. Investors should watch whether the AI‑driven redeployment of mining hardware restores earnings stability, or if prolonged low prices force further exits, reshaping the Bitcoin mining landscape.
