Heard about it, never looked into it. I've seen mixed reactions. I'll check what I can understand.

I'm just not pro altcoins because they have no value outside their unit of mesurement for energy/time/utility/scarcity. There is no sense to have different unit for the same concept. Just as having both metric and imperial unit have no utility.

We just need ONE monetary unit with the best attributes, and we know there is just one.
