Bitcoin hashrate hits record 1 zettahash for the first time

The Bitcoin network has reached a historic milestone — for the first time ever, its hashrate exceeded one zettahash per second (ZH/s). On Friday, April 4, intraday peak reached around 1025 EH/s, according to Glassnode data.
 

The 7-day moving average also hit a record on April 6, peaking at 897.6 EH/s. On April 5, mining difficulty surged to an all-time high of 121.51 T (+6.81%). The next recalculation, expected in 11 days, is projected to result in a 0.5% decrease.
 

Profitability Under Pressure

While the hashrate hits new records, Bitcoin’s price has been moving in the opposite direction. On April 7, it temporarily dipped below $75,000 before rebounding to around $80,000. Still, it remains nearly 30% below its all-time high in January.
 

According to Hashrate Index, the hashprice (revenue per PH/s) has dropped to a yearly low of about $40 per day — more than twice lower than a year ago before the April 20 halving. In Q1 2025, miners earned just 1.33% of their total revenue from transaction fees.
 

Shift Toward AI and HPC

Amid declining profitability, mining companies are turning toward high-performance computing (HPC) and AI sectors. Bitfarms signed a preliminary agreement with Macquarie Group for a $300 million loan to develop the Panther Creek project — an asset it acquired through a merger with Stronghold.
 

Meanwhile, Galaxy Digital entered a 15-year deal with AI company CoreWeave. Under the agreement, it will provide 200 MW of infrastructure at the Helios data center in Texas, which it previously purchased from Argo. Galaxy expects to generate up to $4.5 billion from the contract.
 

However, U.S. miners may face additional pressure from the “liberation tariffs” proposed by Donald Trump. Industry experts warn that these new import duties could directly impact the mining sector.
