The Coldcard is my fav hardware option by far. This unassuming little calculator has so many features that most people never even realize are there. If you haven't dove into yours yet, here's an in depth walkthrough starting with the basics, then moving into the more advanced features.

After my original tutorial, Nunchuk added support for Coldcard NFC, so I made this follow up video as well.

Of course I've got a ton of free videos on all this stuff, but if you're in Miami for the conference in May, I'm holding a 4 hour workshop and there are a few tickets left. Anyone who needs more hand holding and wants to attend will come out of this thing super proficient with their calculator skills.

The Coldcard - because who needs a fancy hardware wallet when you can have a trusty calculator with hidden talents? Plus, you can always use it to balance your checkbook in between crypto trades.

Paper wallets are one of my favourite features. Last minute presents sorted many times by that handy feature. 🧑

And Seed XOR

I use the NFC option of the coldcard with Nunchuk wallet to make payments to my lightning node on Android.

Nunchuk ofc on Android, not my lightning node

Coldcard is 'Bitcoin standard' grade hardware.

BIP-85 is one of my favorite features that ColdCard supports.

One seed to rule them all!

Ok so the wallet functions are cool and all but like Ben, I've watched this tutorial multiple times now and I don't see the part where you show me how to use the calculator function. I bought this fancy calculator since I was told it was the only one that could calculate 21/♾️

Keep up the good work πŸš€
