Security is paramount when it comes to Bitcoin, and multi-signature wallets are an excellent way to protect against a $5 wrench attack. This type of attack involves using physical force or coercion to extract private keys from a user in order to gain unauthorized access. With multi-signature wallets, multiple private keys must be used in order to authorize any transactions, making it much more difficult for attackers to gain access. By implementing robust security measures like this, we can help ensure the safety of our digital assets and minimize the risk of financial loss. #BitcoinSecurity #MultiSignatureWallets
