Yep, I agree with all that.
Any time I see reference to Nostr elsewhere people's first experience is; a firehose of bitcoin/scammy/christian/libertarian stuff that's really in need of moderation...
That's pretty much what people see, like it or not.
People that have tried a bit harder say they've been fleeced transferring crypto to sats with even the popular wallets compounding the scammy perception.
It's going to be a difficult base to grow from imho.
