Japan’s SBI Crypto has officially announced that it will shut down its Bitcoin mining pool on July 31, 2026, marking a significant milestone in the restructuring of the global mining industry. For everyday investors holding Bitcoin—currently trading at 61,659 USD—this sudden exit of a top-15 global pool, combined with wild shifts in mining difficulty, signals a crucial period of consolidation that could reshape how the network is secured and how it impacts your portfolio.

The Hardware/Software Landscape
To understand why this shutdown matters, it helps to think of a Bitcoin mining pool like a cooperative sweepstakes syndicate. Instead of one person buying a single lottery ticket and hoping to win, a group of people pools their money to buy thousands of tickets, agreeing to share any winnings. In the Bitcoin world, miners combine their computing power into these pools to increase their chances of solving the cryptographic puzzle required to win new Bitcoin. When a pool succeeds, the reward is shared among all participants based on how much computer power they contributed.
SBI Crypto, a major subsidiary of Japan’s financial giant SBI Holdings, has been a key player in this system for years. The company ranked approximately 12th globally by hashrate, representing about 2% of the total computing power on the network. However, the company recently announced that its mining pool will stop accepting mining shares at 22:00 UTC on July 30, 2026, with all pool operations officially wrapping up on July 31, 2026. While SBI Crypto did not disclose the exact reason for the shutdown, the move is widely seen by analysts as part of a broader corporate pivot away from mining infrastructure toward retail exchange services and stablecoins.
Miners currently using SBI Crypto‘s pool are being urged to migrate their computing power to alternative service providers, including Braiins, Luxor, and NeoPool. This shift illustrates the dynamic nature of the hardware and software landscape. While individual miners will keep their physical computers running, the coordination software they use is shifting to new players, showing that the network’s virtual labor force remains highly mobile and resilient.
Hashrate & Difficulty
The closing of SBI Crypto‘s pool comes during a highly volatile period for the Bitcoin network. Two key concepts define this volatility: hashrate and difficulty. Hashrate is simply a measure of how many worker machines are actively mining on the network at any given time. Difficulty is the automatic program built into Bitcoin that adjusts how hard it is to mine a new block. If many new miners join, the game gets harder; if miners turn off their machines, the game gets easier. This ensures new blocks are found roughly every ten minutes—like a puzzle game that automatically adjusts its difficulty level depending on how many players are in the room.
Throughout June, the network experienced dramatic adjustments:
- June 14, 2026 — At block height 953,568, the network executed a massive 10.09% downward difficulty adjustment, dropping from 138.96 trillion to 124.93 trillion. This was one of the largest downward adjustments of the year, triggered by miners turning off their machines as profit margins shrank.
- June 27, 2026 — Just two weeks later at block height 955,584, mining power surged again, leading to a 7.15% upward adjustment that pushed difficulty to 133.87 trillion.
- Daily Hashrate — The network’s total computing power has recently hovered in the range of 945 EH/s to 975 EH/s (exahashes per second), showing that despite individual pools shutting down, the overall network security remains near record highs.
The next automatic difficulty adjustment is estimated to take place between July 8, 2026 and July 11, 2026, with analysts predicting a minor change of less than 2%. For regular investors, these adjustments prove that the Bitcoin network is self-stabilizing. Even when a major player like SBI Crypto exits, the network adjusts to keep running smoothly without any central authority stepping in.
Profitability Metrics
Why are big players like SBI Crypto stepping back from the mining pool business now? The answer lies in the thin margins currently facing the industry. The Bitcoin halving in April 2024 cut the amount of Bitcoin awarded to miners in half. With Bitcoin currently trading at 61,659 USD and the network difficulty sitting at a high 133.87 trillion, miners must spend more electricity than ever to earn the same amount of cryptocurrency.
When the price of Bitcoin is flat or declining, less efficient mining hardware becomes too expensive to run. Only the largest operations with access to cheap electricity and the most advanced hardware can maintain healthy profit margins. For retail investors, this means the mining sector is professionalizing. Instead of amateur hobbyists running rigs in their basements, mining is increasingly dominated by large, highly efficient corporate entities that treat computing power as a commodity.
Environmental Impact
A central part of the conversation around Bitcoin mining is its environmental footprint, which is also driving how corporate pools operate. The Bitcoin network’s total annual energy consumption is estimated to be between 138 TWh and 204 TWh, representing roughly 0.5% to 0.8% of all electricity consumed globally. While these numbers are large, the industry has made significant strides in adopting clean energy.
According to current industry estimates, the sustainable energy mix (combining renewable sources like hydro and solar with carbon-free nuclear power) powering the Bitcoin network now stands between 52% and 56%. Furthermore, miners are increasingly serving as flexible loads for local power grids. Because mining machines can be turned off instantly, operators can absorb excess green electricity during off-peak hours when solar and wind power are abundant, and shut down their operations when local grids face high demand. This symbiotic relationship is helping utilities fund and build more renewable energy infrastructure.
Strategic Outlook
Looking ahead, the exit of SBI Crypto and the ongoing shifts in hashrate point to a mature future for the network. While the loss of a pool representing 2% of the network will cause a temporary redistribution of computing power, it poses no threat to the security of the blockchain. In fact, new financial products are emerging to help bridge the gap between traditional finance and mining infrastructure. For instance, HashKey Capital recently launched a first-of-its-kind Bitcoin Hashrate Fund, which allows professional investors to buy shares in computing power directly, earning a yield denominated in Bitcoin rather than relying solely on the price of the asset.
For the average investor, this consolidation and financial innovation are positive signs. The underlying infrastructure of Bitcoin is shifting from a speculative tech experiment into an institutionalized global commodity. While short-term swings in difficulty and the closure of older mining pools might capture headlines, the network’s automatic self-correcting mechanisms ensure that your digital assets remain secure.

2% hashrate gone just like that. wonder who absorbs that, probably Foundry or AntPool
SBI was one of the most respected pools in asia. them leaving says way more about mining economics than any analyst report
japanese regulators made it impossible to run profitable mining domestically. SBI held on longer than most expected
SBI pulling out of mining is a bigger deal for Japan than people realize. there is basically zero domestic pool presence left after this
^ exactly, and with electricity costs in Japan being what they are, nobody is filling that gap domestically
difficulty keeps climbing, margins keep thinning. only the mega-ops survive now. this is what consolidation looks like
difficulty has been brutal for smaller pools all year. SBI probably ran the numbers and saw the margins were gone post-halving
