Really sorry to hear that 😞

But I don't this is only for Rira-san, as for most people it's possible to earn sats (net terms after accounting for zaps given) on Nostr in its current state. Maybe if there's more options to load from fiat like in Primal and the user base also increases, it's possible but doesn't seem very likely next year.

As per nostr.band stats only 800-900 people receive zaps daily & average zaps are 2800 zap amount is 5-10 sats.

I see Rira-san being very generous whenever you zap - thank you for that kindness 🙏
