Bitcoin Hardware Wallet Tutorial - Using ColdCard's Air-Gapped Feature

Part of my ongoing series of Bitcoin education videos. Here I show you step by step how to send a Bitcoin transaction using a ColdCard hardware wallet, using the air-gapped feature. I also explain in general how Bitcoin transactions and wallets work and the difference between hot and cold wallets and a private key is and why hardware wallets are more accurately called "Signing Devices" and not wallets.
