Every transaction is permanently recorded in a public ledger. That seems centralized. Also you have no idea who centrally controls it or how much bitcoin is still in circulation. It's not actually used as currency for daily transactions. It's a fraudulent store of value and is worthless in a crisis. no one is going to give you ammunition or guns or food or gasoline or electricity or land in exchange for your bitcoins unless they are fools. Now that bitcoin is on the jewish stock exchanges it will become more speculative and fraudulent than ever.

You will own nothing (digital make believe bitcoins) and be happy.
