Visión general de la red

Another week, another uphill climb for miners. Bitcoin’s network difficulty is set to rise by nearly 4% tomorrow, one of the sharpest increases since the halving. The adjustment reflects renewed miner interest driven by recent price strength, but it also signals intensifying global competition. For high-efficiency operators, it’s a chance to solidify their lead. For others, it may mark the beginning of the end.

While difficulty has held steady until now, a dip in BTC price has dragged down miner revenues. Transaction fees remain respectable, but they’re not making up the difference. The mempool grew slightly, pointing to steady demand for blockspace, but with lower transaction value, that demand may be more noise than signal. One way or another, the coming week looks like a test of resilience for much of the mining sector.

North America, Eurasia, and Latin America Dominate Bitcoin Hashrate Distribution

The Q2 2025 Bitcoin mining heatmap from HashrateIndex shows that the United States remains the global leader in Bitcoin hashrate, accounting for 36.03% of the network. Russia is steadily gaining ground at 15.65%, while China, despite bans and crackdowns, still maintains 13.73%. China is likely achieving this through smaller-scale or unofficial operations in hydropower-rich provinces like Sichuan and Xinjiang. Canada holds 2.92%, bolstered by renewable energy access in regions like Quebec and British Columbia.

Other active mining regions include Paraguay (3.60%), Kazakhstan (2.48%), the UAE (3.73%), Oman (3.11%), and Iran (1.24%). Paraguay’s Itaipu Dam continues to draw attention with its abundant hydropower, while countries like Iran and Kazakhstan have used mining to monetize surplus energy or bypass economic sanctions. In contrast, large parts of Africa, Southeast Asia, and the Middle East remain mostly inactive due to high electricity costs, weak infrastructure, or political barriers.

Overall, the global mining landscape continues to be shaped by energy economics and regulatory climates, with North America, Eurasia, and select Latin American countries firmly established as today’s Bitcoin mining hotspots.

Private Mempools Pose Centralization Risks for Bitcoin

While the public mempool aligns incentives between users and miners, private APIs and off-chain submission mechanisms (like Marathon’s Slipstream) create opaque transaction flows. These systems let miners accept transactions that don’t propagate through standard relay channels, bypassing censorship or delays, but at the cost of transparency and decentralization.

As more miners adopt private APIs or third-party solutions like mempool.space, the fee market may be distorted, and smaller miners face a disadvantage due to overhead and revenue sharing. Second-layer systems like Lightning could also be compromised, as private mempools make it harder for users to monitor time-sensitive transactions. The rise of fragmented or parallel mempool networks introduces complexity and UX friction, ultimately reinforcing centralization by favoring large miners with direct access to private order flow.

Bitcoin Miner Revenues and Exchange Inflows Rise, But Market Has Room to Grow

Bitcoin miner revenues have climbed to $51.6 million per day, sign of a healthy and active network, though still below the previous cycle’s peak of over $80 million. This could herald continued upside potential for miners if the bull market strengthens. Miner inflows to exchanges have also doubled recently, from 25 BTC to 50 BTC per day, following Bitcoin’s recent all-time highs.

Despite the uptick in sales from miners, the market has absorbed the added supply without major disruption. These trends suggest Bitcoin is still in a growth phase, not yet at cycle exhaustion. Analysts estimate the next peak could reach between $200,000 and $250,000, with the potential for higher highs if institutional demand grows in response to economic instability.

VanEck Proposes Miner Royalties to Build Strategic US Bitcoin Reserve

VanEck’s head of digital assets research, Matthew Sigel, has proposed a royalty system for US Bitcoin miners to fund a federal Bitcoin reserve without taxpayer expense. Speaking at the 2025 Bitcoin Conference, Sigel suggested that miners contribute a small portion of their block rewards to the Treasury, which could be mandated through budget reconciliation or embedded into legislative bills. This approach would be budget-neutral and modeled after federal royalties from oil and gas extraction.

Sigel also advocated for tax exemptions for miners who use waste methane, linking environmental benefits with BTC accumulation. These miners could operate mobile rigs on flared gas sites, earn tax-free rewards, and forward a royalty share to the reserve. The plan aligns with Trump’s March executive order to build a Strategic Bitcoin Reserve and could help the US “stack sats” while reducing emissions and strengthening national financial resilience.

Bitmain Launches Antminer S23 Hydro, Market’s Most Efficient Mining Rig

Bitmain has introduced the Antminer S23 Hydro, a new mining rig delivering 580 TH/s with a power draw of 5,510 watts, achieving a market-leading efficiency of 9.5 J/TH. Announced at the World Digital Mining Summit 2025, the launch comes amid declining demand for mining hardware following the 2024 Bitcoin halving, which halved block rewards to 3.125 BTC. The S23 Hydro is designed to help miners remain competitive by cutting operating costs.

Bitmain is also adjusting to market conditions by offering flexible payment terms, including installment plans and bitcoin-backed reservations. ASIC buyers now enjoy more leverage, with firms like CleanSpark and HIVE negotiating favorable deals. First shipments of the S23 Hydro are expected in Q1 2026, with early buyers receiving discounts. As mining margins shrink, efficiency and energy costs have become critical for survival.
