Five Pools Dominate Bitcoin Mining. Who Decides Whether Your Payment Gets Through?

Your keys. Your Bitcoin.

But who decides whether your payment gets confirmed?

The five largest mining pools account for roughly 80% of daily blocks in a recent 30-day average.

Independent miners supply the computing power. Under conventional pooling, pool operators usually choose which transactions that power works to confirm.

That’s a distinction every Bitcoiner should understand.

Your keys can remain secure while your valid payment waits for a willing miner.

Bitcoin’s defenses depend on keeping those alternatives open—and giving miners more control over what they mine.

When a pool says no, who still has the power to say yes?
