I went nostr only because I only used Twitter. Had 15k followers but I could tell I was shadow banned during covid and nobody would ever reply or see my tweets. After going nostr only I enjoy the feed and interaction more. 
If I were you I would keep the other platforms for now but try to slowly move your followers over to nostr  

 Great advice 

 Yep, that’s what my intuition has been telling me. Little by little
