hmm
crypto
currency without price?

Yes! The value could instead of price be in the information about users/usage. Simply the attention from users is perhaps valuable enough to be put in a block chain. I'm just speculating here and haven't thought it through yet.

I have no idea how it can exist, if u will find any examples let me now about it here
In my previous post I described the really big picture. Technological singularity stuff. Won't happen until around the year 2045 according to Ray Kurzweil. Still, I think the idea of a free cryptocurrency could become a viable alternative, maybe already today.
The core idea is that people's attention is the fundamental resource. Take a Facebook like for example. How much is that worth in monetary terms? Quite a lot, even in terms of real money. How much is an ad click worth? The idea is to have a cryptocurrency that captures that value of user engagement and gives it an objective measurement.
