In this video I show you guys how to send and receive Bitcoin to your ColdCard MK4 and how to set it up from scratch so you can use it as a fully air gapped hardware wallet.

The ColdCard is the most secure best Bitcoin wallet ever created and the MK4 is packed full of new features like NFC. However I think the best use for the ColdCard is as a deep cold storage device that lets you control your keys in a fully air gapped setup utilizing partially signed Bitcoin transactions and the Sparrow wallet to interact with the Bitcoin network.
