In my place, it's hard to convince people what BCHNostr is all about because they're not aware about BCH yet. So i told them about BCH first, what it was, how it works and what they can do with it.
I showed them trading platforms like cauldron, coins and bitcoin.com.
Told them what a wallet address is, the importance of the seed phrase,and how to keep it. After that, i innocently opened BchNostr in front of them and used their curiosity against them. And that is how i spread the word. Haha.
