Your Bitcoin is protected by one key.

One key that can be:
- Stolen
- Lost in a fire
- Found by the wrong person
- Extracted under duress

There's a better way.

Multisig = multiple keys required to move funds.

2-of-3: Three keys exist, any two can sign a transaction.

Lose one key? You still have two. Someone steals one? They can't spend without another.

Where to put the keys:

- Key 1: Your hardware wallet at home
- Key 2: A second device in a separate location
- Key 3: A trusted family member or safety deposit box

Geographic distribution = resilience.

Multisig eliminates:

- Single point of failure (lost key doesn't mean lost Bitcoin)
- $5 wrench attacks (attacker needs multiple locations)
- Inheritance problems (family member already holds a key)

The tradeoff: complexity.

Multisig requires more planning, more devices, more coordination.

But for serious holdings ($10K+), single-sig is the bigger risk.

We set up multisig configurations in our concierge sessions. Hardware, software, backup strategy - all of it.
