Graduate to Multisig

Time Required: 10 minutes

🎯 When You Hit $10,000

Single-signature wallets are great for getting started.
But when your Bitcoin is worth serious money, it's time to upgrade your security.
Multisig = Multiple keys required to spend.

What Is Multisig?

Multisig (multi-signature) means multiple keys must approve a transaction before Bitcoin can be spent.

Simple Analogy

Single-sig: 1 key = 1 door lock. Lose the key = lose your Bitcoin.
2-of-3 multisig: 3 keys exist, any 2 can unlock. Lose 1 key? Still secure.
3-of-5 multisig: 5 keys exist, any 3 can unlock. Maximum redundancy.

Why Multisig Matters

Protection from loss: Lose 1 key? Still have backup keys.
Protection from theft: Thief needs 2+ keys, not just 1.
Protection from coercion: No single point of failure under duress.
Inheritance planning: Family members can hold keys collaboratively.
