So a rewards program by vape companies in exchange for letting them track every detail (exactly what you're vaping, how much and when) of your usage, free advertising if you try and sell/hype up the "crypto currency" (essentially transferable rewards points) and a loyalty incentive (you have to use our catridges with our pen otherwise the mining tech doesn't work).

That actually isn't too far fetched. I think the hard parts would be manufacturing the monitoring/mining tech cost effectively but otherwise if you had the credentials to make it happen and pitched it to a few vape companies you'd probably get a bite fairly quickly.
