Unpopular opinion:

If you're single entity, you don't need multisig.

Multisig enchances security only if you're an expert in key management and have high technical knowledge about how multisig works. For others, multisig actually weakens the security by introducing more complexity and ways to lose your coins, forever.

In this poll by a Norwegian podcaster, only 13,5% respond that they store their #Bitcoin in multisig.

- 44,9% store their generational wealth with singlesig
- 35,3% store their hard money at an exchange
- 13,5% store their Bitcoin in multisig
- 6,4% store their BTC in a hotwallet

Why choose multisig and eliminate single points of failure?

By requiring multiple private keys to authorize transactions, multisig eliminates single points of failure, enhances security and flexibility, making it ideal for both individuals and organizations.

To the 35,3% storing your Bitcoin at an exchange. Avoid custodial solutions. Self-custody is critical. If you don't control your private keys, you don't truly own your Bitcoin. “Not your keys, not your Bitcoin.”

Honeypots like exchanges will continue to get hacked. With higher Bitcoin prices, exchanges will be even larger goals for hacks and thefts.

Singlesig wallets, where one key controls everything, are simple but risky. They involve a single point of failure. Lose the key, and you could lose your Bitcoin forever. Multisig, however, removes this single point of failure by requiring multiple keys for transactions.

In a multisig setup, multiple private keys are required to authorize a transaction. This is represented as “m-of-n,” where ‘m’ keys out of ‘n’ total keys are needed. Common setups like 2-of-3 or 3-of-5 strike a balance between security and ease of use.

Multisig offers enhanced security. If one key is lost or compromised, your Bitcoin is still safe with the remaining keys. It’s a safeguard against loss, providing peace of mind that singlesig cannot match. A lost mulitisig key can also be replaced.

Beyond individual security, multisig is perfect for organizations and businesses. It enables collective control over funds, preventing any one person from unilaterally spending Bitcoin. Businesses, non-profits, and even families can benefit from this collaborative approach.

Multisig also acts as a disaster recovery tool. If one key is lost, the remaining keyholders can still access the funds. This ensures that Bitcoin isn’t lost forever due to a single point of failure, which is a significant risk with singlesig.

Multisig can facilitate trustless escrow transactions. By involving a neutral third party as one of the keyholders, funds are only released when all parties agree. This minimizes the risk of fraud and disputes, making Bitcoin transactions more secure. Example HodlHodl

For estate planning, multisig allows for secure and resilient transfer of digital assets. By distributing keys among trusted family members or advisors, you can ensure your Bitcoin is passed on securely, preventing any single party from gaining full control.

While multisig provides superior security, it comes with trade-offs like increased complexity and higher transaction fees. However, the protection it offers often outweighs these drawbacks, especially for long-term storage of significant amounts of Bitcoin.

Setting up a multisig wallet involves choosing a wallet that supports multisig like SparrowWallet by craigraw (npub1hea…g9v2) , configuring the m-of-n setup, and distributing keys securely. Testing the setup with small transactions is crucial before using it for significant amounts.

Multisig enables separating your keys geographically. This buys time, increases risk for attackers, and limits their ability to compromise all keys at once. Dedicated hardware wallets representing each key also add an essential security layer.

For those who prefer some expert support, collaborative custody is an option. You maintain control of the majority of keys, while a trusted partner holds one key. Unchained, Casa and Nunchuk have excellent inheritance services built on collaborative custody.

#Bitcoin multisig is a powerful tool for anyone serious about securing their Bitcoin. Individuals, businesses, organizations, can utilize multisig for enhanced security, disaster recovery, and collaborative management of funds, making it a cornerstone of Bitcoin security.
