When the price pumps later this year, the no-coiners will start listening to bitcoiners more. Theyll realize that if the bitcoiners were right about bitcoin, maybe they’re right about nostr. Nostr activity goes up with the bitcoin price.
One way X could mitigate this is by introducing their own fiat zaps to compete, but I doubt they’ll have the foresight to do this. Even if they did, nostr still has the advantage of decentralization.
