every crypto says it's out there to chage the world , obviously most will not be able to do this even given the best of intentions, so in the long run the fail-rate is going to be way above 90%, couldn't be otherwise, as they are all competing to replace major infrastructure.
what I would like to see is a crypto project that sets out with more modest goals, and still has a viable groth strategy, use case and business model.
don't give me revolution - give me evolution
