The Grand Rapids Bitcoin Meetup gathers for a private, self-guided demonstration session to educate anyone needing technical guidance on air-gapped key migration.
A critical vulnerability has been disclosed regarding seed phrases generated directly on Coldcard devices. If you generated your seed phrase on-device, your funds should be migrated to a newly generated setup. Setups utilizing dice rolls or external generation are unaffected.
Privacy & Opsec Assurances:
- Completely anonymous: No check-in, names, or sign-ups.
- Zero disclosure: You do not need to show your screen, seeds, or balances to anyone.
- Flexible: You can bring hardware to work through the process locally, or simply observe the step-by-step walk-through and perform the migration at home.

โจ The Grand Rapids Bitcoin Meetup is for anyone with an interest in Bitcoin, regardless of if you own any. We are focused on education first. This is a “Bitcoin-only” group. We are focused on Bitcoin education and do not discuss other “cryptos.”
