But overall the good thing is that the price is going up on avarage, with every mint the "floor" price is higher. This week is 0.17, week before was 0.15, and so on. I see that average daily volume is also increasing, which is good.
Market price is driven by demand and supply as in any other coin, but the reason the price goes up is of course the gold coverage price (price of gold behind every xaurum, where the ammount of gold is getting higher and higer).
Reason why mint pushes the price up to the production price is because mint must first buy on the market if the price is lower, since obviously the supply is sufficient if the price is lower. At last mint the market price was higher than production price and that resulted in no market buy.
