The Bitcoin mining industry is undergoing a turbulent period, marked by soaring production costs and a record-breaking network hashrate.
This surge reflects not only the pressure from the all-time high network difficulty but also rising energy costs and fierce competition among mining companies.
How Much Does It Cost to Mine One Bitcoin in 2025?
According to the latest report from TheMinerMag, the average cost to mine one Bitcoin rose from $52,000 in Q4 2024 to $64,000 in Q1 2025. It continued to climb past $70,000 in Q2 2025, a jump of over 34% in just two quarters.
“First-quarter filings from major Bitcoin mining companies highlight a rising cost of production, driven by both the surging network hashrate and, in some cases, higher energy prices,” the report explained.
TheMinerMag noted that Bitcoin’s mining difficulty has exceeded 126 trillion. Data from Coinwarz supports this, with charts showing a sharp increase in recent years.
Bitcoin mining difficulty measures how hard it is to find a valid block on the Bitcoin network. It doesn’t have a specific physical unit. Instead, it’s a relative index compared to Bitcoin’s original difficulty when the genesis block was mined in 2009. A difficulty of 126 trillion means it is now 126 trillion times harder than at the beginning.
What’s Driving This Difficulty Surge?
The increase in difficulty is fueled by a 14-day average hashrate reaching 913.54 EH/s, just 10% short of the zetahash milestone (1,000 EH/s).
Hashrate represents the computing power of the entire network to perform hash operations and find valid blocks. A higher hashrate means more miners, tougher competition, and smaller profit margins.
TheMinerMag attributes the rising hashrate to rapid expansion by large mining firms.
“The recent rise in Bitcoin’s network hashrate has been driven largely by public mining companies scaling and energizing new capacity. Leading firms such as MARA, CleanSpark, IREN, and Riot have all reported increases in realized hashrate,” the report added.
However, while hashrate growth strengthens the network, it comes at a cost. Hashprice — a metric that measures how much a miner can earn per unit of hashrate — has dropped to just $52 per PH/s.
More concerningly, TheMinerMag revealed that Bitcoin transaction fees have plummeted. Fees made up only 1.3% of block rewards in May and fell below 1% in June — a historic low. This puts added financial pressure on miners, who rely heavily on block rewards to cover costs.
Bitcoin Mining Firms Diversify Amid Rising Competition
Mining stocks don’t necessarily track Bitcoin’s price. TheMinerMag’s report highlighted a growing divergence in miner stock performance, reflecting differences in how companies adapt.
“The growing divergence comes despite Bitcoin’s relatively stable price, highlighting a decoupling between BTC and mining stocks. This trend suggests that equity investors are increasingly evaluating miners based on their adaptability in the post-halving environment — particularly their ability to pursue new narratives — rather than simply mirroring Bitcoin’s price movements,” the report said.
In response, major mining firms are diversifying their revenue streams to reduce reliance on Bitcoin’s price.
For instance, Riot doubled its Bitcoin-backed credit line with Coinbase to $200 million. Meanwhile, MARA allocated 500 BTC to Two Prime to expand its yield strategy. Other firms are shifting into high-performance computing (HPC) and AI hosting to counter shrinking mining profits.
As the cost of mining Bitcoin continues to rise and profitability narrows, mining companies face a tough decision: adapt or fall behind.
