"we are buying a physical gold to backing all exsisting Xaurums...and than normaly gold backing pushing the price up."
No, there isn't an automatic equalizer- there have been times when there has been a three cent difference between xaur price on exchanges and xaur production price. Also, the price on c-cex is sometimes 3 cents lower than the highest exchange.
With these 3 cent differences it's only a matter of time before a program is made to buy xaur from the cheapest exchange in order to sell on a different exchange and that creates artificial trade volumes- you can't claim the marketing is working when machines are doing the buying and selling.
I'd like the dev's to enquire as to who is buying xaur right now so that if required, an alteration can be made in order to steer in the right direction.
