Can't I use my #bitcoin npub and nsec for #nostr ?

Yes, they use the same algorithm, which is secp256k1

So you see my point .. #nostr is an inspiration from #bitcoin .. may be we should ask Fiatjaf :-) ..
But again my point was that of reach .. #bitcoin reach is only to people who value and understand monetary assets .. social media reaches pretty much everyone :-)
