While many expected Bitcoin mining profitability to drop in 2025 due to major crypto price swings and regulatory uncertainty, the sector proves just the opposite. Fueled by strong network activity and surging transaction fees, BTC mining revenue jumped to new heights, proving the resilience of the crypto ecosystem.
According to data presented by CryptoPresales.com, Bitcoin miners raked in a staggering $7.86 billion in the first half of 2025, the highest H1 figure in the crypto market’s history.
With $1.5 Billion in Revenue, May Ranked as the Fifth-Highest Month on Record
Each time Bitcoin’s price drops or stays weak, like in early 2025, miners earn less for each block they add to the blockchain. Since mining rewards are typically paid in BTC, any price drop reduces the dollar value of those rewards, even if the number of coins mined stays the same. However, transaction fees also tend to fall during a slowdown due to less trading and network activity, meaning miners take a double hit.
The 2025 crypto market slowdown hit miners hard, with falling Bitcoin prices, decreased network activity, and shrinking transaction fees wiping out hundreds of millions of dollars in earnings. According to data from The Block, Bitcoin miners made $3.86 billion in Q1, or $900 million less than the same period last year. This massive double-digit drop pushed miners’ revenue back to 2022 levels, when they raked in around $3.4 billion in Q1 and faced a similar 17% year-over-year decline. The average monthly revenue also plunged, falling by 17% to $1.28 billion in Q1 2025, down from $1.55 billion in the first three months of last year. However, the trend reversed in the second quarter of the year.
Bitcoin mining revenue recovered in Q2 2025 as transaction fees spiked due to network congestion and increased on-chain activity, including the use of Ordinals and Layer 2 tools. Also, Bitcoin’s strong performance in May boosted miners’ earnings, despite ongoing market turbulence. As a result, revenue surged to $4.05 billion in Q2, with May alone bringing in $1.5 billion, the fifth-highest monthly total on record. Altogether, miners made a record $7.86 billion in the first half of 2025, beating the previous highs of $7.71 billion in 2024 and $7.34 billion in 2021.
Mining Stocks Still Struggle Despite Record Revenue
Despite generating a record $7.86 billion in revenue in the first six months of the year, Bitcoin mining stocks still struggle to fully recover after the April plunge. According to Companies Market Cap data, the combined market capitalization of the world’s five largest crypto mining companies, Marathon Digital Holdings, Riot Blockchain, Core Scientific, Iris Energy, and CleanSpark, stood at $21.8 billion in January. By mid-April, that figure had plummeted 44% to $11.64 billion, following a sharp $900 million revenue drop in Q1.
Since then, their combined market cap has rebounded to $23.2 billion as of last week, only 9% above January levels, driven mainly by the standout performance of Iris Energy. Despite the April slump, the Australian crypto miner’s stock value surged 72% year-to-date, reaching $4.2 billion last week.
Other Bitcoin mining giants saw much smaller gains, or no gains at all. For example, the world’s largest Bitcoin miner by market cap, Marathon Digital Holdings, is up just 2.5% year-to-date, sitting at $6.8 billion. On the other hand, Riot Blockchain and Core Scientific saw declines of 3.6% and 1.4% year-to-date, with market caps of $4.5 billion and $4.2 billion, respectively. CleanSpark sits in the middle, posting a 16% year-to-date gain and a $3.5 billion market cap as of last week.
