The world needs #Nostr and #Bitcoin, not vice versa.
I think people need to discover bitcoin first. Nostr comes after.
For me it was the opposite. When I met Nostr I understood the importance of Bitcoin.
I bought Bitcoin years prior, but Nostr definitely solidified some principles and got me resolved to ditch my Ethereum. It's nice if people pick up Bitcoin the right way first, but Nostr makes it easier to share all of the potential pitfalls that so many of us already hit so others don't have to.
Definitely not necessary to go this order. Nostr is a lot more accessible in a matter of a couple minutes. Even if you're using an awful KYC exchange and sending a bank wire to fund your purchases it's likely going to take you a few hours to actually buy some bitcoin, unless you're given a hardware wallet and are nearby a bitcoin ATM. Besides, come to Nostr first, get a lightning wallet, and you'll likely end up getting zapped at least a few sats to start your stack anyway.
