Hey. I'm new on Nostr. At the moment on iris but still learning to use that on my mobile. Also want to use other nostr apps mostly for selling digital art, where to start? I'm also on Plebeian market and also still learning to use that. Can't use damus as my device and country isn't supported. Haven't been using WhatsApp for 2wks now. Any guidance to sell my digital art for sats? Highly appreciated.
