Content content content. Bluesky has a massive liberal bias. So unless you’re that you won’t want to be there. 
NOSTR  has a massive bitcoin, and developer bias. So if you’re not that then you won’t won’t to be there. 
Ask yourself how many people in the world care about those things, and if you care to broadcast your reach further. If you do then put lightning in the background, and diversify the content. If not that’s cool continue what’s your doing. For what it is currently it’s a successful grouping of those people. If you want more then ask what people want. Unfortunately that’s stupid cat videos, and not bit coin.
