Bitcoin Braces for Largest Mining Difficulty Plunge Since 2021 as Hashrate Tanks
Bitcoin's backbone is cracking—miners are pulling plugs as profitability evaporates.
The network's computational power just hit a cliff edge, triggering what could be its most dramatic difficulty adjustment in four years. When the hashrate craters, the protocol self-corrects—but this time, the freefall looks more like a market verdict than a temporary blip.
Wall Street's crypto tourists won't feel this pain. Their paper Bitcoin keeps printing while the actual network bleeds raw computing power. Meanwhile, the OGs who keep the lights on are getting squeezed between energy costs and dwindling rewards—proof-of-work's brutal economics at play.
Next difficulty epoch? Expect blood in the water. The machines have spoken.
Profitability metrics spell mining stress
Data from CryptoQuant contributor IT Tech shows that Bitcoin miners are now “extremely underpaid.” Per the analyst, the market is in a phase of forced selloffs from mining operations to stay afloat.
In recent weeks, the sustainability metric has dropped DEEP into negative territory, with an uptick in selling power, meaning miners are leaning towards letting go of their holdings and away from mining.
Miners were fairly compensated during periods when Bitcoin traded in the $90,000–$105,000 range between March and May. Yet, since early June, the profitability is almost entirely eroded.
CryptoQuant’s Bitcoin: Miner Selling Power (log-scaled) chart reveals a downturn in the selling strength of miners. The metric, which accounts for how much Bitcoin miners are capable of offloading into the market, has hit a new low.
As of June 24, difficulty and hashrate values, a single miner operating at 390 TH/s and consuming 7,215 watts of power at $0.05/kWh WOULD generate a mere $11.76 per day in profit. It would now take 5,156 days, more than 14 years, to mine a single Bitcoin under these conditions.
Mining power slides as geopolitical differences bite
On June 22, the United States launched targeted airstrikes against Iranian nuclear facilities. While not confirmed officially, it is believed that power stations may have been impacted.
Iran legalized Bitcoin mining in 2019 and built up a sizable network using subsidized electricity from fossil fuels and nuclear plants. At its peak, Iran accounted for approximately 4.5% of the global Bitcoin hashrate. The figure now stands closer to 3.1%.
Following the US strikes, there have been several reports of blackouts and digital network disruptions from both Iran and neighboring Israel. The outages could have affected mining facilities, either damaging or forcing them to shut down due to power loss.
Some analysts observed a sharp decline in Bitcoin’s hashrate earlier this week, with the network’s computational power dropping by 8% between Sunday and Thursday. The hashrate reportedly fell from 943.6 million terahashes per second (TH/s) to 865.1 million TH/s.
The market has so far rebounded against the backdrop of US President Donald Trump’s announcement of a “total ceasefire” agreement between Iran and Israel. Word from TRUMP seemingly helped restore investor confidence, pushing Bitcoin back up above the $106,000 level on Monday. At the time of this report, the largest coin by market cap is changing hands around $105,300.
