Who really controls $BTC?

Not the devs. Not the miners. Not even the whales.

It's the nodes. Always has been.

You run a node = you enforce the rules. No one can change consensus without YOUR permission.

That's the whole point. That's why it works.

Decentralization isn't a buzzword. It's your ability to verify every single transaction yourself.

Stop asking who controls Bitcoin. Start running a node.
