“At every meetup, we'll start with a brief discussion about that meeting's topic and then open it up to the group to chat and ask questions.”
New here? Just show up. Nobody will ask what you own, and you don't need to own any bitcoin. Come with questions. Never share your seed phrase with anyone, at a meetup or anywhere else.
Stay safe. Meetups listed here are run by their own organizers, not by this guide. A real meetup will never ask you to send bitcoin to join, to "verify" anything, or for your seed phrase. Meet in public places.
