A micropayments platform like Patreon or merchandising where fans buy products? Mircopayments is incredible hard because payment provider backends charge a percentage plus a minimum fee. Never mind that any support interaction (1-2 emails or chat) can bring revenue down to zero, the platform would need a huge amount of active paying users. I support three Youtubers via monthly Patreon (positive impact on my life is limited).
