SBI Crypto to Wind Down Bitcoin Mining Pool as Hashpower Consolidates

Japan’s SBI Crypto is stepping back from mining infrastructure. The SBI Holdings subsidiary said it will discontinue its Bitcoin mining pool on July 31, keeping operations and payouts normal until the shutdown. No rationale was provided. The service has run since at least 2017 and currently ranks as the 11th largest Bitcoin pool by hash rate, per Hashrate Index. The pool also supports Bitcoin Cash and Litecoin.

The headline isn’t just that a sizable pool is closing—it’s where that hashpower migrates and what it signals about the business model. SBI is already facilitating “business and technical discussions” for clients with other operators, including Braiins and Luxor, noting some may extend special terms to incoming customers. That proactive handoff matters. In a tougher revenue environment—Bitcoin is trading more than 50% below its $126,080 all-time high set last October—margins compress and miners often prefer scale, liquidity, and predictable payout schemes. Capital then concentrates with a few specialized pools that can offer PPS/PPS+ stability, deep firmware/tooling stacks, and robust risk controls.

Consolidation improves uptime and service for many participants, but it also nudges network topology toward larger coordinators. That can influence template selection policies, transaction filtering norms, and the cadence of client upgrades—subtle levers that shape miner behavior over time. When a prominent pool exits and routes clients to a short list of providers, those soft-power dynamics strengthen. Operators like Braiins and Luxor are sophisticated and well-regarded, but the industry should still keep an eye on how fee structures, block assembly policies, and compliance postures evolve as share grows.

There’s a second signal embedded here: compute is being repriced. Over the past year, some large mining firms have redirected capex to AI infrastructure, striking multi-billion-dollar deals with major tech companies even while maintaining some Bitcoin exposure. A notable example: publicly traded miner Bitfarms said last year it would fully wind down mining as it shifted to AI and rebranded to Keel Infrastructure. Public markets often reward that pivot—AI demand appears steadier, contracts can be longer-dated, and the revenue stack is less tethered to spot BTC volatility. In that context, exiting a mid-tier pool looks less like capitulation and more like shedding a lower-ROIC, higher-operational-complexity line.

For SBI Holdings, the crypto strategy isn’t retreating—it’s rotating. Earlier this week, the parent company agreed to acquire Japanese exchange Bitbank for $289 million. That move leans into regulated, fee-based services with clearer unit economics, while stepping away from a capital-intensive segment with tightening spreads. It’s a cleaner portfolio: market infrastructure and custody on one side, compute-heavy mining on the other.

What should miners do now? - Evaluate pool migration on total economics: fee schedule, payout method, stale rate, latency, and historical variance. - Consider jurisdiction and policy posture, including transaction selection practices. - If you mine BCH or LTC alongside BTC, confirm multi-coin support and hardware compatibility. - Negotiate transition incentives; SBI notes some operators may offer preferential conditions.

SBI Crypto’s pool will keep running through July 31, with customers continuing to mine and receive payouts as usual until closure. Expect near-term hash rate to shuffle rather than disappear. The larger story is the steady specialization of mining services and a capital rotation toward AI compute, while incumbents like SBI redeploy into exchanges and broader digital asset infrastructure.
