I'm actually in a bitpac called The Meshtadel. Every member had to contribute 11k sats to join and there are 15 of us. We used some of our money to pay someone to manage a private nostr relay for us for 1 year as a kind of backup for our nostr notes. https://bitpac.org/index.html?multisig=80865e0b7039ab3d12ea54308cbcb0088e8e9323d20b620077804aec9afca3ef
