I was onboarded to bitcoin ten years ago on Twitter. If not for ChangeTip, I never would have bought any. 

I would rather onboard precoiners onto nostr than say "Buy bitcoin." You should not "invest" in things you don't understand.

Nostr is like Galt's Gulch on the Internet.  We use #bitcoin. This is not an asset you send your fiat to a financial institution in the hopes of getting more fiat. It is peer-to-peer electronic cash. You might want to get some in case the money printer go brrrrrr breaks the economy, but do what you want
