I have this little vision of companies using coins as a way to reward loyal customers and this idea can really be applied to any company that wants to maintain and increase their user base really.
I have thought of things like Uber Coin, You earn like 1 coin per ride or 1 coin per mile and after you reach lets say 10 coins you get 1 mile off your trip, so you could eventually lets say get 100 uber coins after riding 100 miles and get a 10 mile trip for free, you know rewarding constant use of their service, of course the numbers are just an example and they can be tweeked but it would be pretty cool.
Supermarket loyalty cards? a thing of the past! Say hello to X Supermarket coin instead, for every 10$ spend you get 1 supermarket coin that can be used to take 10c off any product and if you eventually gather enough coins you could get somethings for free, its like a crypto version of customer loyalty.
I think loyalty programs for sure are just around the corner.
