In my opinion, it's very risky to backed any coin by gold nowadays. gold price isn't a stable at this time.
sorry, but I don't agree with you buddy.
gold can be said to be the only one that has a stable price from time to time.
so I don't hesitate at all.
Stability is relative, but even for gold you can say that it goes through quite volatile times every now and then.
But still can't compare to btc for instance, i don't even see the point of argument in this idea, i personally think the ppt team have made a great choice to back XAUp with Gold rather than any other currency,
Maybe if other tokens/coin where pegged in other currency/commodity from the beginning other than btc, we won't be experiencing such high level of volatility and instability in price.
