Hey, welcome! I came into Nostr with pretty much the same assumptions and decided to also check it out for myself. Over the years I've learned that sometimes people's opinions are correct, but other times, it's best to actually look into things yourself, and in this instance, I'm glad I did.
I'm also not too huge into bitcoin, but I've been all over crypto for years, ETH, BTC, even made a ton of NFTs before Opensea killed royalties lol
