I understand the incentive for people to run their own Bitcoin node. But forthe life of me I can't grasp why anyone would want to run a Nostr relay, can someone explain?

Is there a potential on Nostr to make 1 million sats a month posting 3d/digital art I create? I'm really curious. #asknostr #nostrart

Any updates on self-custodial bitcoin layer 2 thats fast, easy, cheap and offers non frictional unilateral exit? #asknostr
