Phishing Attempt: The "Post-Quantum" Snail Mail Scam targeting Coldcards ????????

​Apparently if I don't scan this (totally legitimate) QR code by June 30th, the quantum computer boogeyman is going to come after my sats.

​I have to hand it to these guys, they really know what they're doing and it honestly makes me feel uncomfortable how much info they have on me. They even knew I owned a Coldcard. But sending physical letters through snail mail to protect an air-gapped wallet from future quantum threats like true cypherpunks is peak comedy—especially when their cutting-edge security solution is just telling me to scan a sketchy QR code with my phone.

​Just a heads up for anyone else who gets this, it’s a highly targeted physical phishing campaign (probably from an old database leak like Ledger or a shop breach). Coinkite is never going to mail you a letter asking you to scan a code or sync your device.

​Remember, stay safe and don’t scan or open any links. Keep your keys offline!
