I'm traveling and a MS update completely bricked my laptop. Caught in an endless cycle of reinputting my Bitkey thing or whatever. Finally got it working by completely wiping and redownloading Windows, though of course that means I'm starting from scratch like a new computer.

Recently picked up a Bitkey for my Bitcoin. I’d fully recommend it as a cold storage solution once they roll out their inheritance solution next month.
Easy setup and use.

🙄 falls wer denkt, der hiesige Milliardär sei irgendwie vernünftiger, als der von drüben.
Screenshot der Meldung: “Bitkey: Jack Dorseys neue Bitcoin Hardware-Wallet enthüllt.” Darüber ein Foto von Jack Dorsey. Foto eines Bitkeys: ein sechseckiges flaches Objekt, wirkt ein bisschen wie ein marmorierter Stein, mit einem kreisförmigen Einlass an der vorderen Ecke. Der Bitkey liegt in einer möchtegern edlen Pappschachtel.
