Bitcoin Mining Difficulty Plummets Nearly 8% as AI Boom Lures Miners Away
Bitcoin's network security is flashing a critical warning sign as mining difficulty just plunged 7.76%—the steepest drop since China's 2021 crackdown—signaling a potential 10% correction from its January benchmark. The dramatic shift comes as computational power is rapidly redirected toward the booming artificial intelligence sector, causing Bitcoin blocks to slow to a concerning 12 minutes and 36 seconds, forcing the network's automated recalibration.
BTC mining companies have been shifting to AI data centers
The network’s average computational power has been declining since it hit its all-time high in mid-October 2025. With total hashrate sliding from 1.15 ZH/s to 940 EH/s, the nearly 8% difficulty drop gave hashprice a nice bump back above $33 per PH/s daily. According to industry specialists, the average breakeven point for miners is near $40 per PH/s per day.
In early February, when difficulty plummeted by 11%, the primary factor was Winter Storm Fern, which knocked an estimated 200 EH/s offline. However, by February 20, a record 14.7% correction followed as hashrate surged past 1,000 EH/s. At the moment, most analysts think the drop in difficulty is linked to industry participants diversifying into more lucrative AI services, rather than to temporary fluctuations.
For some time, BTC mining companies have been working hard to reinvent themselves as indispensable partners for hyperscalers like Meta, offering the infrastructure needed to win the AI race. Those massive cooling systems and electrical contracts once used for Bitcoin are now being flipped to power the next generation of AI.
Nevertheless, the transition is not as easy as it seems. Companies still need to install more advanced cooling and network systems to support a new fleet of AI-focused graphics cards. Nevertheless, AI giants save a fortune by piggybacking on the miner’s existing land and power.
Over the last year, CleanSpark secured $1.15 billion in funding for data center expansion. The firm, nonetheless, continues to prioritize its core Bitcoin mining activities. Major Bitcoin mining company Core Scientific also began its transition to AI in 2024. Its first AI deal back then quadrupled its share price, and its stock gained 10% in 2025. The firm is even planning to turn off its last Bitcoin rig, completing its exit from mining and focusing entirely on AI data centers by 2028.
“The opportunity for miners to convert to AI is one of the greatest opportunities I could possibly imagine,” said Adam Sullivan, chief executive of Core Scientific, a Bitcoin mining company that is transitioning into AI data centers.
Morgan Stanley predicts that US data centre power demand will surge by 74 gigawatts between 2025 and 2028. So far, the U.S. is facing a 49 GW deficit in its 74 GW demand; converting Bitcoin facilities could recover 10 to 15 GW, significantly narrowing that gap, according to the bank.
Thiel says the Bitcoin network needs to grow by 50% to bolster mining profitability
Fred Thiel, CEO of MARA Holdings, shared his frustrations with BTC mining late last year. He argued, “Bitcoin mining is a zero-sum game. As more people add capacity, it gets harder for everybody else. Margins compress, and the floor is your energy cost. [ . . . ] The global hashrate keeps growing, which means everyone else’s margins keep shrinking.”
He warned that Bitcoin’s original economic “safety net” isn’t holding up as intended. According to him, the network was designed with the expectation that transaction fees would eventually cover its costs, but that shift has yet to materialize. He explained that between 2028 and 2032, the financial pressure on the network will only skyrocket unless it hits a 50% annual growth target to make up for the missing fee revenue.
He added that they intend to slash production costs to improve profitability.
