I believe Tripally is a good candidate for that

. Their tokens have a real meaning:
1 token = 1 day of unlimited mobile internet in a foreign country. Right now I believe they sell their tokens at the ICO price of 60 cents.
If they will be successful in implementing their idea, which I believe they will judging from their whitepaper, you can expect the price go x10-x20.

If one token will represent one day of data - how would the price increase unless the price of data increases?
AirFox will do something similar, but the client won't see the token their end from what they have said, in order not to confuse people.
