SBI Crypto Halts Bitcoin Mining as Top Three Pools Capture 60% Share

Japanese miner SBI Crypto ceased Bitcoin operations with 0.72% share, while Foundry, AntPool, and F2Pool collectively held 60.01% of network hashrate.

Woofun AI reports that SBI Crypto terminated its Bitcoin mining service on July 31 at 11:22 UTC, dropping to a 0.72% share equivalent to 6.8 exahashes per second. At that moment, Foundry, AntPool, and F2Pool collectively accounted for 60.01% of attributed blocks, with Foundry leading at 26.67%. This concentration reflects a transient snapshot rather than permanent control, as individual pool metrics fluctuated. Foundry, AntPool, and F2Pool showed lower estimated hashrates in the partial July 27 bucket compared to the prior week, while Luxor increased and Braiins decreased. The specific routing behind SBI Crypto's lost hashrate remains obscured within aggregate totals.
