Coldcard is an ‘only-Bitcoin’ hardware wallet mostly recommended for mid-high knowledgeable/experienced bitcoiners. If you are a newbie, I´d recommend you using Trezor as your standard hardware wallet. However, it doesn´t provide the same level of privacy and security.

This is a step by step practical tutorial. I won’t dive into any explanation of the Coldcard wallet itself. For further information about it you can click on the links below:

One of the unique features of the CC wallet is the ability to perform offline transactions through PSBT (Partial signed Bitcoin transaction) with a microSD card.

CC wallet can get started using an external battery with no need to connect it to your computer, unlike Ledger and Trezor which both require to connect them to the computer everytime they’re being used.

Tutorial
