How can Auroracoin be the 4th crypto-coin by market cap if it's unreleased yet?
Turns out I was wrong. It is mineable right away and it is actively being traded in different exchanges, as cryptorush.in and cryptsy. What hasn't happened yet is the release of the pre-mined coins (50% of final amount), which will be given to Icelandic citizens.

Too bad the official page isn't clear about this (info on pools and exchanges is a bit hidden in the forums), nor does it list anywhere a list of exchanges dealing with it or pools for mining it - the cryptocointalk page linked first states all that.
