You wrote: "...and a mint can only happend if the price increase."
This is not correct, the mint can happen regardless on the price. Maximum 30% of money will go to market buy the rest for new gold. New mints will happen as soon as new "payment ways" for Brazil and Australia will come to life.
I think the team will not wait anymore for the price to increase.
with their spread when buying gold, of course minting is to expensive...
Xaur team - maybe you should learn from this graph - this is how I believe Xaur should be acting when market is volatile...

maybe you shudln't concentrate so much on MLM (which I guess is profitable only for you and not token holders) but on smart PR and opening new exchanges
