but why 5, you need to reconsider having more than 3, you will get fatigue managing that because there's no way that the gutter trash client devs are gonna make that easy for you
I just realized that I have six, as I retired the first one.
I run two organizational npubs (GitCitadel and PurpleKonnektiv), have one for gitstuff (Silberengel), one for testing (Testerin), this one and then the retired one (Pipe, previously Stella).
