How Risky is it to invest in Iraqi Dinar?

Many people refer to the Iraqi Dinar currency as an "investment". It is actually more speculative or even a gamble. I would think of it as a lottery ticket. I doubt a "revalue" as the Dinar community puts it will happen but I'd hate to miss out on it if it does so I have invested an amount of money I am prepared to lose and actually expect to lose but hey if something big happens great.
