According to Bitcoin.com, in May, the total revenue of Bitcoin miners reached $1.086 billion, breaking the $1 billion mark for the first time since January, with block subsidies accounting for $1.079 billion and transaction fees contributing minimally. However, with the decline in Bitcoin prices, miners are facing profitability pressure.Hashrate has dropped from the 1000 EH/s range to below 975 EH/s, and daily revenue per PH/s (mining price) has decreased from $37.44 a month ago to about $30.77, a decline of 17.82%. The block output interval has extended to 10 minutes and 49 seconds, and it is expected that the network difficulty may decrease by 7.5% around June 13. The proportion of transaction fees in the block reward has rebounded from less than 0.6% to about 1.16% in the past 24 hours, providing a slight buffer for miners.

Bitcoin Treasuries.NET posted on platform X that Michael Saylor from Strategy stated that the annualized operating rate of STRC reached 24 billion dollars, which alone buys 2 to 3 times the Bitcoin output of miners. Strategy has purchased 11 billion dollars in BTC so far this year, with a buying speed that has reached 2 times the output speed of miners.

According to Bitcoin News monitoring, a transfer from the Satoshi era Bitcoin miner has appeared on the blockchain again, with an early Bitcoin miner whale transferring 2,650 BTC to institutional trading firms FalconX and Cumberland, worth approximately $203 million. The miner still holds about 6,000 BTC, valued at over $460 million.

According to Onchain Lens monitoring, a Bitcoin OG miner from the Satoshi era deposited 2,650 BTC ($203 million) into FalconX and Cumberland.This OG whale still holds 6,000 BTC, worth approximately $462 million.

According to Bits Media, the Russian government has expanded the scope of information that miners and mining infrastructure operators must submit to the tax authorities. Under the new regulations, the national registry of miners and operators must include network address data for equipment used in cryptocurrency mining (ASIC miners). The Russian Ministry of Finance stated that this move aims to simplify the regulation of digital asset transactions and the investigation of violations. Additionally, grid operators will be able to more accurately monitor the infrastructure load in areas with a high concentration of mining capacity.According to the law, government agencies, courts, the Bank of Russia, and grid operators can access the information in the miners' registry. The Federal Tax Service is responsible for maintaining the registry of miners and mining infrastructure operators. Under current law, miners and infrastructure operators (such as mining pools) must submit and regularly update the following information: for mining equipment, details such as manufacturer, model, serial number, algorithm, hash rate, power consumption, and operating mode. Regarding mining: the amount and type of cryptocurrency mined, mining pools, and links to online statistics.

According to Protos, Bitcoin Core developers recently disclosed a high-risk vulnerability numbered CVE-2024-52911, which affects versions 0.14.1 to 28.4, allowing miners to remotely crash other users' nodes and execute code by mining specially crafted blocks.The vulnerability was discovered and responsibly disclosed by developer Cory Fields in November 2024. The fix was merged in December of that year and released with version v29 in April 2025. The last vulnerable 28.x version series was discontinued on April 19, 2026.However, since upgrading Bitcoin full nodes is voluntary, it is estimated that about 43% of nodes are still running the vulnerable old version software, facing potential risks. Fortunately, the cost of implementing such an attack is extremely high—miners would need to allocate significant computational power to mine invalid blocks that do not yield block rewards—so it is likely that it has never been exploited in practice.

According to CryptoQuant analyst Arab Chain, the number of Bitcoin miner deposit transactions has significantly decreased recently, with the current reading at approximately 8,138 transactions, one of the lowest levels in history. This data once exceeded 100,000 transactions by the end of 2025, reflecting a large amount of Bitcoin deposited by miners, which is usually associated with selling intentions or profit-taking. However, since the beginning of 2026, this indicator has shown an overall downward trend, with no clear peak.The current selling pressure from Bitcoin miners has significantly eased, which may provide additional support for the market. The decrease in transaction numbers not only indicates a reduction in deposit amounts but also suggests a lower frequency of transfers to exchanges, reflecting a more conservative behavior among miners.

In the first quarter of 2026, public Bitcoin miners sold over 32,000 BTC, setting a record liquidation, while shifting capital towards AI infrastructure due to rising mining costs.

According to monitoring by Lookonchain, the miner "3PFNdg" sold 265.19 BTC, worth 18.06 million USD. It is reported that the last time this miner sold Bitcoin was 2 years ago.

Data shows that the economic pressure on Bitcoin mining is intensifying. The current average production cost per coin is about $88,000, while the current Bitcoin price is approximately $69,200, meaning miners are losing nearly $19,000 per BTC, resulting in an overall loss of about 21%. Meanwhile, the overall mining difficulty has decreased by about 7.8%, marking the second-largest drop within 2026, reflecting the exit of computing power and rising network pressure.Analysis suggests that rising energy prices, combined with the tense situation in the Middle East, further increase mining costs. Electricity costs remain under pressure, and if miners are forced to sell Bitcoin to maintain operations, it could create additional selling pressure on the market. If Bitcoin prices continue to stay below the cost line and difficulty continues to decrease, the process of miners clearing out may continue, putting pressure on the spot market structure in the short term.

Matthew Sigel, Head of Digital Asset Research at VanEck, stated on social media that the average price of Bitcoin dropped by 19% on the 30th, but the spot price has stabilized. Market volatility has significantly decreased, with realized volatility falling from 80% to 50%, and the futures funding rate dropping from 4.1% to 2.7%. On-chain activity has cooled down, with transaction volume decreasing by 31%, daily average fees reducing by 27%, and the distribution speed of long-term holders slowing down.On the miner side, they have largely maintained a "mine and sell" strategy, selling almost all newly issued Bitcoins. Defensive sentiment in the options market has peaked, with the ratio of put/call open interest averaging 0.77, reaching a new high since June 2021; the premium of put options relative to spot trading volume has reached a historical high of 4 basis points.

According to CoinDesk, the conflict in the Middle East leading to rising oil prices has caused a significant drop in Bitcoin's hash rate, putting pressure on miners and the overall market.In the past week, the network hash rate has decreased by about 8%, to 920 EH/s, suggesting a possible entry into a new phase of miner sell-offs, which is usually accompanied by downward price pressure. The current Bitcoin price is below $72,000, down about 5% from Monday's peak. The network is expected to undergo a hash rate difficulty adjustment of about 8%, marking the second-largest negative adjustment in the past five years. Previously, in mid-February, Bitcoin also experienced a historic significant difficulty adjustment, indicating extreme volatility in mining activity.Analysis indicates that the pressure faced by miners stems from intensified competition, persistently low transaction fees, and Bitcoin price fluctuations, which have compressed profit margins. Many publicly listed mining companies have begun to diversify their operations, including AI and high-performance computing, while increasing Bitcoin sales to maintain operations, which also creates some resistance to Bitcoin prices.

According to Crowdfund Insider, Binance has upgraded its lending services, launching an improved Flexible Loan product that allows users to obtain liquidity without selling their assets.This product is an over-collateralized, open-term isolated lending solution, with a minimum loan amount equivalent to 1 USD. It supports borrowing and repayment at any time, and no fees are charged for either. The collateralized assets will automatically connect to the Simple Earn flexible product, continuously generating earnings every minute, achieving "earn interest while collateralizing." The loan interest rate is also refreshed every minute to reflect real-time market conditions. Borrowed funds can be used for spot trading, leveraged positions, contract trading, or further staking, with supported assets including mainstream tokens like BTC, ETH, and USDT.The platform has a built-in risk monitoring mechanism, but users still need to actively manage their positions and maintain sufficient collateral buffers to prevent forced liquidation. Binance stated that this upgrade is particularly suitable for long-term holders like Bitcoin miners, allowing them to cover operational costs or seize market opportunities without reducing their asset holdings.

According to market news, the Federal Tax Service of Russia announced that cryptocurrency miners will pay approximately 567 million rubles (about 7 million USD) in taxes to the state in 2025, of which 84 million rubles will be personal income tax and 483 million rubles will be corporate income tax. This figure is far lower than the previously expected 6 billion rubles (about 74 million USD).Officials pointed out that factors leading to the reduction in tax revenue include: rising electricity prices in Russia, high global hash rate of the Bitcoin network, a declining dollar to ruble exchange rate, falling Bitcoin prices, and limited legalization of mining. Russia legalized mining through legislation in 2024, requiring legal entities and individual entrepreneurs to register with the tax authorities, but currently, more than two-thirds of mining companies have not yet registered.

According to Jin10 data reports, there are market rumors that Japan and other Asia-Pacific countries plan to reach a $30 billion energy and mineral agreement with the United States.

According to on-chain data platform CryptoQuant, the selling pressure from Bitcoin miners has intensified. MARA announced a new policy allowing the sale of Bitcoin reserves and transferred 298 BTC to Cumberland; Core Scientific recently also sold 2,174 BTC.MARA's current average mining cost is about $70,027 per coin, while efficient miners can have costs as low as approximately $45,000. The purpose of the sell-offs by several mining companies includes strengthening their balance sheets and funding the expansion of AI infrastructure.
