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.
