That does sound like a good idea.
I have been wondering about a multi-currency account. I am a newbie at all of this so please don't take this that I know anything. But my understanding of a multi-currency account (MCA) is that it holds the currency digitally. In other words, if I deposit 100,000 dinar and 5000 USD, both of those amounts would be held in that manner. I was thinking it may be a good idea for 2 reasons. If there is a time limit on how long we have to turn in the dinar, we could deposit it and the physical dinar would be sent in. Then we could exchange dinar for USD at the current exchange rate as desired. We would only pay taxes on the amount that is exchanged. That is my thinking, anyway. I need to consult a financial advisor once it RVs and I have the money to pay for the advice.
