Anyway, the majority of players are still buying and selling for 1 refined. Although most of my proof has 0.66 business, i think this range is more suitable, cause i'd say 70% of the trades are still 1 ref based. However it is already kinda easy see trades for less.

Feel free to say what you think. :)
