SBI ends mining pool
SBI Crypto, a cryptocurrency-focused division of Japanese financial conglomerate SBI, announced it will shut down its Bitcoin mining pool and stop accepting mining shares on July 31, ending a service it launched in March 2021.
“SBI Crypto is ending its Bitcoin mining pool service, the 11th largest according to Hashrate Index.”
Decrypt reported SBI Crypto would cease operations on July 31 and that the firm wrote, "Until then, we expect the pool to continue operating under normal conditions, and customers may continue mining and receiving payouts as usual."
CryptoDnes.bg said the shutdown will remove up to 2.2% of global hashrate, with the company confirming its Bitcoin mining pool will shut down by July 2026 and stop accepting new computing tasks at 22:00 UTC on July 30.
CryptoNews.net said SBI Crypto would end mining pool operations on July 31 and stop accepting mining shares at the same time, while urging miners to keep directing hashrate to the pool until the cutoff so final payouts can be calculated correctly before operations end.
Hashrate shift and timing
SBI Crypto set a transition window by telling customers to keep directing their computing power to the pool until the final moment, with CryptoDnes.bg saying it will stop accepting new computing tasks at 22:00 UTC on July 30 and cease operations one day later.
CryptoDnes.bg added that market estimates suggest the closure will remove approximately 15 exahashes per second (EH/s) from the Bitcoin network, representing between 1.3% and 2.2% of global hashrate depending on methodology.
CoinDesk said SBI Crypto’s mining pool accounts for roughly 2% of the Bitcoin network's total hashrate, and that the firm urged customers to keep mining with the pool until the cutoff so eligible shares are included in the final payout calculation.
CryptoDnes.bg also reported SBI Crypto recommended miners migrate to Braiins, Luxor Pool, or NeoPool to facilitate the transition before the service officially ends.
Strategic pivot beyond mining
While SBI Crypto did not provide an official reason for terminating the pool, CryptoDnes.bg said the move aligns with SBI Holdings’ broader transformation in the digital asset sector, including expanding its crypto exchange business and accelerating stablecoin infrastructure.
“A $21 million hacking incident in September 2025 drained funds from company wallets.”
CryptoDnes.bg cited SBI Holdings’ $289 million deal to acquire full control of the Japanese exchange Bitbank and said the group is supporting the JPYSC project and the distribution of Ripple’s RLUSD in the Japanese market.
Crypto Briefing reported the security incident that looms over the timeline: "A $21 million hacking incident in September 2025 drained funds from company wallets," and it said the stolen assets included BTC, ETH, LTC, DOGE, and BCH.
LCX Exchange framed the closure as the end of SBI Group’s direct involvement in pooled mining, while also noting SBI Crypto’s mining pool ranks No. 12 globally and that the company directed miners toward Braiins, Luxor, and NeoPool for migration.
