Sats back as a reward in place of existing rewards programs or as an onramp to rewards programs for orgs that don't have it is a potential killer app for Bitcoin that will grow adoption massively. I really wish someone was working on a scalable solution for businesses for this. I am a luddite, I can't handle the tech portion of it but I understand the vision of what it should be. I keep hoping some young entrepreneurs run with this idea and I would be happy to invest and advise.
