You're absolutely right, 5 million is still a small part of the huge potential Nostr could reach.

 All it would take is for a few major celebrities to join and adoption would explode. 

With figures like Brazil's, it's clear that the room for growth is enormous. 

If Elon Musk and Pavel Durov really advocated freedom of expression, Nostr would be the place to be.

 But I guess it will just take a little longer for everyone to realize how important this network is 😉
