Not Your Keys, Not Your Bitcoin teaches Bitcoin's core principle: self-custody means you control your private keys—no one else can access, freeze, or confiscate your Bitcoin. Unlike custodial exchanges that can freeze accounts, key management through seed phrase security and cold storage eliminates third-party risk. This defines Bitcoin's value: permissionless ownership no authority can override. Control your keys, control your future. 🔒🛡️

Frequently Asked Questions
What does "Not Your Keys, Not Your Bitcoin" mean?
This phrase captures Bitcoin's core principle: if you don't control the private keys to your Bitcoin, you don't truly own it. Only by holding your own keys in a self-custody wallet do you have genuine ownership that cannot be frozen, seized, or denied by any third party.
Why is self-custody so important for Bitcoin holders?
Self-custody eliminates third-party risk. Exchanges and custodial services can freeze accounts, get hacked, or go bankrupt. When you hold your own keys, your Bitcoin is immune to these risks—you are the sole authority over your wealth.
What is the difference between custodial and non-custodial wallets?
Custodial wallets (like exchanges) hold your keys for you, meaning they control your Bitcoin. Non-custodial wallets give you full control of your private keys, ensuring true ownership. Self-custody means using non-custodial solutions where you—and only you—control access.
