Point taken Vivi 
Though I'm not actually interested in trading the currency for another currency... I'm more interested in trading the currency for items that are useful to me. That's the difference here. You could pump in as many dollars as you want, but what matters here is the trust that fair value is being transferred efficiently and not how much it is worth compared to a dollar. That's just financial garbage. If I can trade 5 xCoins for a kilo of cheese, that makes the coin valuable to me... instead of having to bring the farmer those eggs that haven't been laid yet.
