Bitcoin Difficulty Climbs 3.87% as Hashrate Slips and Next Cut Looms

Key Takeaways:

• Bitcoin difficulty rose 3.87% at block 943488 as hashrate fell 60.45 EH/s; a 15.73% cut is projected.
• Miners face $30.67 PH/s hashprice and 0.56% fees, pushing firms toward AI over BTC mining.
• Bitcoin network nears April 19, 2026, adjustment as slower 11:51 blocks signal easing difficulty ahead.

Bitcoin Mining Tightens

The Bitcoin network has logged a total of seven adjustments this year, comprising three increases and four decreases. The most recent reduction, two weeks ago, was sizable, arriving after consecutive gains of 14.73% and 0.45% across the prior two epochs.

Following the latest adjustment, the difficulty rating is now 3.87% higher, making blocks that much harder to discover, and it further stands at 138.97 trillion times more difficult than Bitcoin’s launch.

As of 4 p.m. Eastern time, 181 of the 2,016 blocks in the current epoch have been mined, placing the network roughly 9% of the way toward the next adjustment expected on April 19, 2026. While it remains early and conditions can shift considerably between now and then, current estimates point to a projected 14.27% reduction.

This outlook stems from a noticeable slowdown in block intervals over the past day, with data from hashrateindex.com indicating an average block time of 11 minutes 39 seconds, well above the expected 10-minute cadence.

What’s behind the shift? A decline in hashrate. Bitcoin.com News reported on March 28 that the Bitcoin network’s total computational power had exceeded 1,000 exahash per second (EH/s), or 1 zettahash per second (ZH/s). On that day, hashpower reached 1,022 EH/s, whereas it now sits 60.45 EH/s lower at 961.55 EH/s.

Revenue Compression Tightens the Squeeze

Compressed revenues are likely a key factor behind the downturn, alongside mining operations opting to allocate resources toward artificial intelligence (AI) infrastructure rather than mining BTC in pursuit of stronger returns. An infrastructure provider deploying its megawatts toward AI rather than mining bitcoin can realize significantly higher returns, a dynamic that has persuaded many of today’s operators to redirect their focus.

A daily hashprice of $30.67 per petahash per second (PH/s) ranks among the lowest revenue levels bitcoin miners have faced since the network’s early years, when bitcoin carried a far smaller valuation. With 106,335 blocks remaining until the next halving, conditions are poised to tighten further.

Adding pressure, miners cannot rely on fees, which account for just 0.56% of the block reward. In effect, the system appears to be approaching a breaking point. Yet Bitcoin’s difficulty adjustment is engineered for precisely this scenario. If miners exit and hashrate declines, difficulty adjusts downward, drawing participants back with more accessible conditions.
