SBI Crypto Is Shutting a 2% Bitcoin Mining Pool

SBI Crypto Sets July 31 Cutoff

The immediate issue is operational. Mining pools aggregate hashpower from many participants, submit work to the Bitcoin network and distribute rewards according to each miner’s contribution. If a pool stops accepting shares, connected miners need to point their machines somewhere else or risk missing rewards after the cutoff.

Reports citing SBI Crypto’s customer notice said the pool will stop accepting shares at 07:00 JST on July 31, equivalent to 22:00 UTC on July 30. Shares submitted after that point will not count toward final payout calculations.

TradingView’s syndication of Cointelegraph coverage said SBI Crypto asked miners to keep directing hashrate to the pool until the cutoff so final payouts can be calculated correctly. The company reportedly thanked customers for their “continued support by mining with us” until the final day.

That sequencing matters because miners usually optimize around payout method, fee rate, stale-share performance and reliability. Moving at the wrong time can leave a miner exposed to missed accounting, delayed payouts or suboptimal pool terms.

The event is smaller than the weather-driven hashrate shock Daily Crypto Briefs covered in Bitcoin’s January hashrate crash. It is still relevant because this time the stress is not a storm. It is a scheduled withdrawal by a corporate pool operator.

Two Percent Hashrate Starts Moving

The 2% figure is large enough to watch but not large enough to threaten Bitcoin on its own. Pool share measures where miners route work for payout purposes, not ownership of the underlying machines.

mempool.space showed SBI Crypto with 13.23 EH/s on a 24-hour view when checked, while SimpleMining’s seven-day snapshot showed 19.69 EH/s and other reports cited roughly 20.9 EH/s from Luxor’s Hashrate Index. The difference reflects time windows and methodology, so the cleanest phrasing is that SBI Crypto sits around 2% of tracked pool hashrate.

For Bitcoin users, the near-term effect should be limited if miners redirect quickly. Bitcoin’s security depends on total active hashpower and economic incentives, not on one pool brand remaining open. The more important short-term question is where the displaced hashpower lands.

If most of SBI Crypto’s miners move to the largest existing pools, the shift could marginally increase pool concentration. If they spread across mid-tier operators such as Luxor, Braiins or smaller options, the closure may redistribute share without materially changing the network’s pool balance.

That distinction is why mining infrastructure is becoming a more visible market story. Bitcoin miners are already under pressure from lower BTC prices, power costs and the capital requirements behind the AI data-center pivot, a theme Daily Crypto Briefs covered in VanEck’s miner funding-gap analysis.

SBI Pivots Toward Exchanges

The pool shutdown lands shortly after SBI Holdings agreed to buy Bitbank in a 46.7 billion yen transaction, about $289 million. That deal, covered by Daily Crypto Briefs in SBI’s Bitbank acquisition, would give SBI a larger domestic exchange footprint and more custody scale in Japan.

The timing does not prove one move caused the other. SBI Crypto did not publicly connect the mining-pool closure to the Bitbank transaction, and the shutdown notice did not disclose a strategic rationale.

Still, the direction is clear at the group level. SBI has been building around regulated exchange operations, Japanese crypto custody, stablecoin distribution and tokenization, while running a mining pool is a narrower infrastructure business exposed to BTC price, hashrate competition and operating margins.

That makes the shutdown a useful signal for the mining sector. Corporate mining services can look durable when prices rise, but the business still depends on sustained miner demand, global competition and predictable payouts. When a bank-linked financial group exits a pool, competitors get a chance to absorb hashpower and prove they can handle institutional miners.

Sentiment remains fragile as miners prepare to move.

The next checkpoints are concrete: whether SBI Crypto publishes final payout instructions, how quickly its reported EH/s disappears from pool dashboards, which pools gain share after July 31 and whether SBI says more about the decision in later corporate updates.
