Network metrics continued to climb last week, with both hashrate and difficulty increasing. As a consequence, miner revenues dropped sharply, driven not only by tougher competition but also by a steep decline in transaction fees, which fell over 26%. Still, the total value of transactions on the network surged, suggesting that on-chain activity remains healthy.

At the same time, the mempool size shrank significantly, indicating that network congestion has eased, which likely contributed to the lower fees. With fewer pending transactions and cheaper block space, fee income dropped further, tightening miner margins. In short, despite a stable Bitcoin price and strong transaction volumes, miners are now operating in a more competitive and less profitable environment. That said, next weekend’s projected difficulty reduction of around 1%, combined with a modest uptick in Bitcoin’s price, may offer some short-term relief.

Russia Pauses Expansion of Crypto Mining Ban, Eyes Relocation Strategy

Russia has suspended plans to expand its regional bans on crypto mining, reversing course amid concerns about declining tax revenue and electricity sales. At a government commission meeting chaired by Deputy Prime Minister Alexander Novak, authorities chose not to impose further restrictions in regions like Khakassia, Karelia, and Penza, and delayed decisions on year-round bans in Transbaikal and Buryatia by two months.

Officials now aim to evaluate economic losses from restricted mining and redirect freed-up power to critical sectors. The Ministry of Energy has been tasked with developing incentives to attract miners to energy-abundant areas of the country, especially those with surplus fuel supplies no longer exported due to sanctions. Though nearly a dozen regions remain under permanent mining bans until 2031, this shift could indicate a more pragmatic approach: regulating and redistributing mining activity rather than outright prohibiting it.

SHA256 Reclaims Top Spot Among Mining Algorithms in 2025

After slipping in profitability rankings last year, Bitcoin’s SHA256 algorithm has returned to the top tier of mining in June 2025, tying with Litecoin and Dogecoin’s Scrypt. The comeback is largely driven by Bitmain’s new Antminer S21e XP Hydro unit, capable of 860 TH/s and generating an estimated $18.24 in daily profit at $0.10/kWh, currently the most efficient mining machine on the market.

Trailing closely is Teckvia’s Volcminer D1 Hydro, while algorithms like Zksnark (used for ALEO) and RandomX (Monero) form a strong second tier, each delivering over $9 daily at moderate hashrates. The shift is part a broader trend in mining: profitability now hinges more on cutting-edge hardware efficiency than coin price alone. SHA256’s resurgence is an example of how innovation can re-establish legacy algorithms in a highly competitive and evolving landscape.

Solo Bitcoin Miner Wins $326K Reward, But Was It Really Solo?

A Bitcoin miner reportedly earned a reward of 3.151 BTC (worth over $326,000) after independently solving block 899,826. This is an extremely rare event in today’s hyper-competitive mining environment. While blockchain data labels the winner as a “solo miner,” experts quickly cast doubt on the narrative.

Dr. CK, administrator of Solo.ckpool (a pool often used by independent miners), suggested the miner had likely rented substantial hashrate, noting a sudden spike in power from a previously low-hashrate account. The term “solo miner,” it turns out, can be misleading: it often refers to any non-corporate or unaffiliated operation, even if it temporarily harnesses significant rented hashpower. Though technically outside of large mining pools, such wins may still rely on industrial-level resources—blurring the line between hobbyist and heavyweight.

AI’s Energy Appetite to Surpass Bitcoin by End of 2025, Study Finds

A new peer-reviewed study in Joule projects that artificial intelligence could consume nearly half of all global data center electricity by the end of 2025, outpacing Bitcoin’s much-criticized energy usage. Researchers estimated that AI demand could reach 23 GW, or 201 TWh annually, compared to Bitcoin’s current 176 TWh.

Unlike Bitcoin’s transparent hash rate-based energy data, AI consumption is shrouded in secrecy. Tech giants like Google and Microsoft report increased emissions tied to AI but avoid disclosing AI-specific figures. This was circumvented by tracing advanced chip packaging data from TSMC, estimating Nvidia alone used nearly half of global capacity in 2023–24. With capacity set to double in 2025, and mega-projects like OpenAI’s $500B Stargate underway, AI’s power demands appear poised to soar.

Marathon Digital Hits Post-Halving High With 950 BTC Mined in May

Marathon Digital (MARA) mined 950 BTC in May 2025, its best monthly performance since January 2024 and a 35% jump from April. The company won 282 blocks, up 38% month-over-month, setting a new internal record. This surge was powered by its vertically integrated operations and the MARA Pool, which retains full rewards and consistently beats network luck by over 10%.

Marathon’s realized hashrate rose 30% to 58.1 EH/s. Alongside CleanSpark and Riot, the combined hashrate jump of 15.5% contributed to pushing Bitcoin network difficulty to a record high, squeezing profitability across the sector. Despite intensifying competition, Marathon held all BTC mined in May, growing its reserves to 49,179 BTC.

Riot Platforms Expands Into AI and Cloud With Data Center Veteran Hire

Riot Platforms has hired Jonathan Gibbs as Chief Data Center Officer to spearhead its expansion beyond Bitcoin mining and into enterprise-grade AI and cloud infrastructure. Gibbs, who has led over $17 billion in data center developments across multiple continents, will guide the launch of Riot’s new data center division targeting clients with high-performance computing needs.

Riot plans to leverage its existing 1.7 GW of power capacity to support the initiative, aiming to “aggressively scale” in response to booming AI demand. The move positions Riot among a growing wave of mining firms pivoting toward broader data infrastructure opportunities as they diversify beyond Bitcoin.
