The absolute BANGER of a usecase for #Nostr is Real Money Gaming (RMG) (1) 

Many governments impose punitive taxes on it. India implemented such tax recently (Nov 2023) (2)

The thing is, that there is huge grassroot demand for it. People will jump hoops to play, a perfect early adopter archetype. 

folks in India are paying 5% to 10% rake on RMG. This is a very cost conscious crowd, and Nostr can do it for much cheaper 

The global market for RMG is ~15 Billion USD, India market is ~2 Billion USD (3)
