Global Crypto Mining News in June: Miner Profitability Hits Record Low, Bitcoin Mining Difficulty Drops Sharply, Stratum V2 Mines Its First Block, etc
1、
JPMorgan said Bitcoin mining economics have continued to deteriorate in 2026, with BTC trading below its estimated production cost of about $78,000 for five straight months. Around 20% of miners are currently operating at a loss. The report said miners have become more sensitive to price moves, as high-cost miners may shut down machines when BTC falls below production cost, pushing down network hashrate and mining difficulty. Publicly listed miners sold more than 32,000 BTC in Q1 2026 to cover operating expenses, exceeding their total sales for all of 2025. JPMorgan expects hashrate and mining difficulty volatility to remain elevated as long as BTC stays below production cost. (The Block)

According to Galaxy Research, Bitcoin completed its 11th-largest mining difficulty decline in history at block height 953,568, with difficulty falling 10.09% from 138.96T to 124.93T, marking the second-largest downward adjustment of 2026. Galaxy Research noted that Bitcoin’s price fell by around 15% in June, squeezing miners’ profit margins and forcing part of the network hashrate offline. As a result, the latest difficulty epoch lasted 15.6 days, longer than the target adjustment period of roughly 14 days.

As Bitcoin recently pulled back to around $62,000 and on-chain activity slowed, Bitcoin mining profitability has fallen to an all-time low, raising market concerns over potential selling pressure. Data from Luxor’s Hashrate Index showed that the estimated daily mining revenue per terahash, or hashprice, dropped to a record low of $0.028 per TH/s on Tuesday, down from $0.039 last month. Taking the Antminer S21 XP Hydro as an example, assuming an electricity cost of $0.07 per kWh, its estimated monthly gross profit fell from $192 last month to $137. Glassnode data also showed that the 14-day average net position change of miner and mining pool addresses has remained negative since early May. (Cointelegraph)

Bitcoin miners’ total revenue reached approximately $1.086 billion in May, surpassing $1 billion for the first time since January 2026. Around $1.079 billion came from block subsidies, while transaction fees accounted for only a small share. Although miner revenue rebounded in May, profitability has come under renewed pressure after BTC recently fell below $66,000. Over the past 30 days, miners’ hashprice declined by about 17.8%, from $37.44 per PH/s per day to around $30.77, while total network hashrate also retreated from around 1,000 EH/s to below 975 EH/s.

Asset manager VanEck said in its latest report that as Bitcoin miners increasingly shift toward artificial intelligence (AI) and high-performance computing (HPC) data centers, total energized power has become the market’s most important valuation metric, given the wide differences in company-level financial disclosures and the still-immature nature of AI-related cash flows. VanEck identified three key dimensions for assessing miners’ transition prospects: the shift from energized power to actual delivery capacity, with the industry currently delivering only about 25% of leased capacity; the severe capital expenditure challenge facing miners moving into AI, including a near-term funding gap of $50 billion and long-term capital needs approaching $221 billion; and the role of tenant credit quality and governance standards in determining financing costs.

The Bitcoin network has successfully mined its first block using the Stratum V2 protocol. Compared with the widely used Stratum V1, Stratum V2 allows miners to independently build block templates and select transactions for inclusion, rather than leaving those decisions entirely to mining pools. While retaining the pool-based reward distribution mechanism, the protocol reduces mining pools’ control over transaction selection and helps improve Bitcoin mining decentralization and censorship resistance.

According to Decrypt, Thailand’s Department of Special Investigation (DSI) recently announced that it has expanded its investigation into a cross-border money laundering network linked to Chinese “grey capital.” The group allegedly laundered more than $300 million annually by recruiting Myanmar nationals to withdraw millions of dollars in cash from Thai banks each day, helping launder proceeds from telecom fraud and illegal online gambling. Authorities have so far seized more than 6,390 mining machines and accused the group of causing around $29 million in electricity theft losses. A key figure in the case, Wang Yicheng, had previously been named by the U.S. Secret Service, with more than $17.8 million in crypto assets linked to pig-butchering scams seized by U.S. authorities.

Paraguay’s National Electricity Administration (ANDE) said a Paraguayan court has convicted two citizens accused of stealing electricity for illegal Bitcoin mining, sentencing both to two years in prison. ANDE said the mining site was directly connected to its medium-voltage grid, completely bypassing electricity payments for mining operations and causing sustained economic losses to the state. The court also made clear that property owners of sites hosting illegal mining operations may also be held liable if they cannot prove they were unaware of the activity, meaning landlords can no longer rely on “not knowing” as a valid defense.

Web3 criminal lawyer Zhang Suhang disclosed that he is handling a suspected illegal business operation case in Qinghai, in which the individuals involved used heat generated by Bitcoin mining machines to provide heating for local businesses before being placed under investigation by public security authorities on suspicion of illegal business operations. Zhang said the dispute in the case centers on whether the conduct constitutes typical virtual currency mining operations, whether relevant regulatory documents can amount to “violating state regulations” under the crime of illegal business operations, and whether the activity reached the level of “seriously disrupting market order.” He argued that the project involved genuine heating demand, around 100 machines, operations mainly concentrated during the heating season, and no significant profits; therefore, the case should not continue as a criminal matter unless the elements of the illegal business operation offense are sufficiently established.

According to Crypto News, Mempool data showed that Bitcoin mined an empty block at block height 954,352. The block was produced by mining pool SpiderPool, with a timestamp of 04:27 on June 19, 2026, and a block weight of 1.16 kWU. The empty block contained only the coinbase transaction, or miner reward, and included no regular user transactions. Notably, it was mined only about 62 seconds after the previous block. Research suggests that such a short interval is usually caused by miners starting to mine with an empty template containing only the coinbase transaction before receiving a full transaction template, in order to gain a time advantage. While a single empty block does not indicate a network failure, miners using this approach also give up the transaction fee revenue that could have been included in the block.

An independent Bitcoin miner using the Braiins Solo mining pool successfully mined block 951,771 and received approximately 3.1404 BTC in rewards, worth around $232,000 at current prices. The miner was operating equipment with roughly 147 TH/s of hashrate, and one Avalon Nano 3S machine, priced at around $300 and producing 6.68 TH/s, was recorded as the device that ultimately found the block. Based on a total network hashrate of around 1 ZH/s, the probability of this device mining a block in a single attempt was approximately 1 in 149 million, meaning it would theoretically take an average of about 2,831 years of operation to mine one block.

According to TheEnergyMag, due to the sharp decline in Bitcoin network hashrate following the early-June BTC price sell-off, Bitcoin mining difficulty is expected to drop by around 9.55% in about eight hours, marking the second-largest downward adjustment of the year. The adjustment will reduce the amount of computing power required to produce blocks over the next two weeks, or one difficulty epoch, thereby directly increasing revenue per unit of hashrate for active miners. Analysts said that if Bitcoin’s price and network transaction fees remain stable, the 9.55% difficulty decline would increase BTC output from active hashrate by more than 9%, potentially pushing hashprice back above $30 per PH/s. In addition to the economic incentive for older mining machines to shut down, another major driver of the hashrate decline is the shift of some power capacity toward high-performance computing (HPC) and AI data centers.
