Secure your Ledger with COLDCARD.
Instead of generating a recovery phrase on your Ledger, derive a BIP85 child seed on your COLDCARD completely airgapped, then restore it to your Ledger.
Your Ledger gets its own independent wallet, while your COLDCARD remains the source.

Our wish this Christmas season is pretty straightforward:
Less bitcoin on exchanges.
More bitcoin properly secured. 🎄🔐

Just got your first COLDCARD?
Try pairing it with @covewallet.
Super clean interface, easy setup, and a smooth workflow for sending and receiving Bitcoin.
Great place to start when learning self-custody. 🔐⚡️

@ronnyavendano_ from the @tbhs_sv has always been very kind with me and very supportive when I needed.
I found the store Booth in @AdoptingBTC yesterday and look what I found 🔥😉 the Coldcard which IMHO is Best Bitcoin hardware wallet.
That's why I teach it to kids in public schools without being paid for it from the company.

If your hardware only works with one app, that’s not self-custody.
COLDCARD lets you build the setup that fits you.
We’re giving away a COLDCARD Q to help someone upgrade their #Bitcoin security.

Your COLDCARD greets you with your personal anti-phishing phrase every time you enter your pin.
It’s like a secret handshake that proves it’s the real deal.
We’ll send a COLDCARD Q to the person with the funniest anti-phishing phrase in the comments.

Closed-source wallets ask you to trust them.
COLDCARD’s verifiable source code lets you check for yourself, no blind trust required.
Don’t Trust, Verify.
