Bitcoin Mining Revenue Falls to Historic Lows

Bitcoin mining is facing its harshest economic environment in years. Falling BTC prices combined with high network difficulty and rising energy costs have pushed miner revenues to historic lows. According to CryptoSlate, Bitcoin is trading near $78,000, more than 38% below its October peak above $126,000.

What appears to be a normal correction from the outside looks far more severe from inside mining operations. CryptoQuant described miners as “extremely underpaid,” citing its profit sustainability index falling to 21, the lowest level since late 2024.

The financial stress is already affecting the network. Bitcoin’s total hashrate has declined by around 12% since November, marking the steepest drawdown since China’s mining ban in 2021. Network security has weakened to levels last seen in September 2025.

Mining economics turn negative

Data from mining pool f2pool shows that at a Bitcoin price near $76,000 and electricity costs of $0.06 per kWh, miner revenue stands at roughly $34 per PH/s per day. Just months ago, spot hashprice exceeded $39, but it has since slid to a historical floor.

Even the most efficient machines are under pressure. Electricity costs consume about 52% of revenue for Bitmain’s Antminer S21 XP Hydro units. Mid-generation rigs, such as the Antminer S19 XP and Avalon A1466i, operate near break-even. Older models generate losses, with power costs exceeding total revenue.

In practical terms, large portions of the global mining fleet are producing Bitcoin at a cash loss, even before factoring in debt, hosting fees, and maintenance expenses.

AI becomes the escape route

This downturn differs from previous crypto winters because miners now have a lucrative alternative. Power contracts, grid connections, and data centers built for mining are in high demand from AI infrastructure providers willing to pay premium prices.

CoreWeave exemplifies this transition. Once focused on crypto, the company pivoted entirely to AI workloads and recently secured a $2 billion investment from Nvidia. In 2025, it attempted to acquire miner Core Scientific, viewing mining sites as prime real estate for GPUs.

Public miners are following the same path. Hut 8 signed a 15-year lease for a 245-megawatt AI data center with an estimated contract value of $7 billion. These agreements provide predictable, long-term cash flows that contrast sharply with volatile mining rewards.

Bitcoin security under pressure

Industry observers warn that some hashrate may never return to the Bitcoin network. Jeff Feng, co-founder of Sei Labs, described the current situation as the largest miner capitulation since 2021. He noted that infrastructure shifting permanently to AI amplifies the decline.

The trend raises a critical question for Bitcoin’s future. If alternative industries consistently offer higher returns for the same infrastructure, the network’s long-term security model may face unprecedented challenges.
