This week’s San Jose Bitcoin Meetup will focus on the recent Coldcard software bug and what it teaches us about securing your bitcoin.
We’ll discuss:
What happened with the Coldcard software bug.
What lessons every Bitcoiner should take away—regardless of which hardware wallet you use.
Practical ways to fortify your cold storage setup.
Reducing single points of failure with backups, seed phrase verification, passphrases, and multisig considerations.
Best practices for verifying, testing, and recovering your wallet before you need it.
Whether you’re new to self-custody or have been securing bitcoin for years, this will be an open discussion focused on improving everyone’s operational security (OpSec).
Bring your questions, your experiences, and your curiosity. As always, there are no dumb questions—only opportunities to become harder to separate from your bitcoin.

All experience levels are welcome—there’s no set agenda, just good conversation and a focus on Bitcoin. No shitcoins here!
These meetups have a simple and singular focus: Bitcoin. All of the topics and discussions will be centered around Bitcoin, the global monetary network, and bitcoin, the reserve asset. If you are interested in crypto tokens, stocks, blockchains, altcoins, alternative investing, NFTs, etc. that is completely fine. There are a number of other meetups to join. This meetup however is just focused on Bitcoin.
Please no photos unless everyone agrees and there are not any other folks in the background. We respect everyone’s privacy.
