.@Ledger fuck you.

@BitcoinRachy COLDCARD... there is no second best.

Quick question that reveals a lot about you as a Bitcoiner: What hardware wallet do you currently use? Ledger? Trezor? Coldcard? Jade? Something else? Drop your answer and tell me why you chose it.

MicroSD 2FA on the COLDCARD adds a physical second factor. Pair it to a specific microSD card and it won’t unlock without it, even with the correct PIN. No card or wrong card = seed wiped. We’re giving away an Mk5. To enter: Like, repost, and comment why you want to win one.

Airgapped isn’t a buzzword, it’s an essential security layer to protect your private keys. COLDCARD Q built for airgapped signing: • QR signing • NFC • microSD Zero need to connect to a sketchy network

Centralized exchanges are like ex-partners: they’re great until they ghost you and take half your stuff. ☠️

Where are your private keys right now? • On your phone? • In a browser extension? • On a device that never touches the internet? This is exactly what devices like COLDCARD are built for. Keeping your keys fully Airgapped.

Your seed phrase is what makes you sovereign. Not the app.
 Not the device. Not the exchange. It's the root of your keys. It gives you and only you ownership of your bitcoin. Stamp your seed into a SEEDPLATE and protect it forever.

Building a TAPSIGNER army 👀 I would argue, using a @TAPSIGNER in place of one of the seeds in a multisig can further increase the security @COLDCARDwallet 👍
