Bitcoin network difficulty reaches a record high: miners face a crossroads between risk and adaptation

The Bitcoin network is undergoing a major overhaul. Last week, the network difficulty increased by 15% — the largest jump since China’s mining ban in 2021. The metric reached 144.4 trillion (T), signaling not just a technical adjustment but deep shifts in the economics of cryptocurrency mining. With Bitcoin priced around $67,380 (as of March 7, 2026), the paradox is clear: difficulty is rising while miners’ profitability is falling.

Hashrate has recovered, but costs remain high

The network’s hashrate has rebounded to 1 zettahash per second (ZH/s) after a recent dip to 826 exahashes per second (EH/s) — the lowest point caused by a winter storm in the US in February. The shift happened quickly: when Bitcoin soared to a record high of $126,080 in October, the hashrate also peaked at 1.1 ZH/s. However, the recovery of computational power has not eased miners’ burdens.

The main pain point is the so-called hashprice, the daily revenue per unit of hashrate. Today, it’s at multi-year lows of about $23.9 per PH/s. This means that even as network capacity grows, each operational hash yields less income. For small and medium-sized miners with high energy costs, this presents a critical challenge.

Why is difficulty increasing when profitability is falling?

The mechanism is simple but harsh: Bitcoin difficulty adjusts every 2016 blocks (roughly two weeks) to maintain a steady block creation rate — one block every 10 minutes — regardless of fluctuations in computational power. When power increases, difficulty rises; when it decreases, difficulty falls.

The recent 15% increase reflects a recovery after February’s crash. But here’s the paradox: difficulty is rising not because miners’ conditions have improved, but because large operators with low production costs continue to mine actively despite shrinking margins. For example, the United Arab Emirates holds approximately $344 million in unrealized profits from mining operations and is not rushing to shut down.

Energy flows into artificial intelligence

One of the main factors shaping Bitcoin difficulty’s future is the shift of energy and computational resources from crypto mining to AI data centers. Several major publicly traded mining companies are reorienting their capacities.

Bitfarms (BITF) recently announced a complete repositioning: the company’s name no longer emphasizes Bitcoin, reflecting a stronger focus on AI infrastructure. Meanwhile, activist investor Starboard is pressuring Riot Platforms (RIOT) to expand into AI data centers instead of traditional mining.

This means that even if BTC prices recover, Bitcoin network difficulty may not grow as rapidly as before. Computing power previously dedicated solely to crypto mining is now competing with a more volatile but potentially more profitable segment — neural network infrastructure.

Large players adapt, small ones survive

Despite pressures on profitability, well-capitalized companies with access to cheap energy continue to stabilize the hashrate. This is critical for network security: a high and stable hashrate is essential to prevent attacks and ensure protocol immutability. But it also indicates a widening divide in the mining industry: large players with economies of scale remain, while smaller miners exit.

The 15% adjustment in Bitcoin difficulty is another signal that the crypto economy has entered a new phase. It’s not just about increasing capacity — it reflects a struggle for survival as energy and capital resources become increasingly scarce.
