nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8 I've been using unleashed.chat, working well so far. What's the cost per token? I see my balance is finally trickling down but am unsure how long that balance will last. Also, are new amounts credited immediately or is there a waiting period?
