Between 1971 and 1973, one Iraqi dinar was equal to 3.21 dollars American. Today, the value is not the same, but financial experts have theorized that the value could go back to what it was. In the interim, there is the opportunity for people to invest in Iraqi dinars at a discounted price, so when the dinar revalues, people will make a profit.
It is up for argument whether it is wise or not to buy foreign currency. Some people believe it is foolish, as values of money may stay the same or decrease. Others believe international currency exchange rates will bring a profit, so they invest in foreign currency.
On the topic of Iraq, since there is a new government in place, they are striving for long term financial stability. As there are online retailers that sell very affordable Iraqi dinars, they are a low risk investment. Iraqi dinars sell online at a range of different prices, and you can get them in a whole bunch of different denominations. And even though an Iraqi dinar can be broken into fils, fils are obsolete due to inflation.
Foreign currency trading certainly is not for everyone. Some people believe foreign currency trading is one of the most foolish things people can do, because of the unpredictability of the value of different currencies. At the end of the day, however, investing in the iraqi dinar is a low risk opportunity for people to make a solid profit, and it is up to you if you want to take advantage of the opportunity.
