SBI Crypto to Close Bitcoin Mining Pool Holding About 2% of Hashrate

Miners who have routed their machines through SBI Crypto's pool have been told to move their hashrate elsewhere before a July 31 cutoff. After that date, CoinDesk reported, the pool will no longer accept contributions, effectively ending its role in the network.

Decrypt characterized the decision as the latest example of a company stepping back from Bitcoin mining, framing SBI Crypto's exit within a wider pattern of firms reassessing whether the activity remains worth the investment.

Why It Matters for European Operators

For mining operations and investors across Europe, the closure is a reminder of how quickly hashrate can shift between pools and jurisdictions. When a pool controlling around 2% of the network winds down, that computing power does not vanish — it redistributes to competing pools, potentially reshaping the concentration of mining power globally.

European miners, many of whom already contend with elevated energy prices and evolving regulatory scrutiny, may see both risk and opportunity. Pools looking to absorb the displaced hashrate could court operators on the continent, while the exit of a well-capitalized financial group underscores how challenging the economics have become even for firms with deep pockets.

The decision also carries signaling weight. SBI is one of Japan's more prominent financial institutions, and its retreat from proprietary mining may prompt other institutional participants — including those in Europe weighing entry or expansion — to reconsider the return profile of running dedicated mining infrastructure versus other forms of digital-asset exposure.

The Broader Picture

Bitcoin mining profitability is tied closely to the price of the asset, energy costs, and the network's difficulty level, which adjusts as more or less computing power comes online. Firms exiting the space often cite these pressures, and the departure of an operator of SBI Crypto's scale suggests that even sizeable players are finding the margins difficult to justify.

As the July 31 deadline approaches, attention will turn to where the redirected hashrate lands and whether the shift alters the competitive balance among the remaining major pools. For now, the immediate task falls to affected miners, who must secure alternative arrangements before SBI Crypto's pool stops accepting their contributions, as both Decrypt and CoinDesk reported.

Senator Kirsten Gillibrand wants to bar members of Congress, the president and their spouses from launching digital assets, following Donald Trump's crypto earnings disclosure.
