I feel like they all fail when it comes to a valuation. For example Wabi - MC $220m based on a token that runs parallel to an RFID tag and offers rewards for use of the tokens when purchasing products that carry the security tag. But why use Wabi? Just for potential rewards? What actually gives Wabi any value? I see the value in Walimai, but what has Wabi got to do with it? Why not just use BTC if you want to use crypto (or believe in crypto)? I think for me this is where it all falls down: there are so many coins and so much promise of potential but no real proven records. I'd be much more confident investing in a company that wants to employ blockchain, rather than a specific coin promising to do what a company does.

Which coins do you think have the best potential and why?
