01
Binance is shutting down its Bitcoin mining pool after six years, effective November 10, 2026.
02
Binance Pool's hashrate share collapsed from 2.3% of the network at the end of 2025 to under 1% by mid-October 2026.
03
Binance gave no financial reason, citing only an ongoing review of its products and services.
04
Pool Savings, Cloud Mining, and the Transaction Accelerator are shutting down too, not just the mining pool.
05
Miners have until 07:00 UTC on November 10 to move their hardware or lose unpaid shares.
06
Foundry USA, AntPool, F2Pool, and ViaBTC already produce the large majority of Bitcoin's blocks.
07
Researchers estimate just three mining pools could theoretically combine to produce over half of all blocks.
08
A true 51% attack remains unlikely and expensive, but pool concentration raises smaller, real risks.
