An introduction to Multi-signature wallets with Bitcoin, using the Casa platform. The managed multi-signature approach is great in that it makes the high level of security accessible to newer users. This video runs through how to create and use a Casa 3 of 5 multi-sig (Keymaster) wallet using a Ledger, Trezor, Keystone and Coldcard. Using Casa provides a great way to get started with Multi-sig wallets, how their backups work and also offers great resources to learn best practices for a secure HODL. Their service is non-custodial, meaning that they can't access your funds and they also provide everything you need to re-create your wallet and recover your funds if Casa disappears.
