think about it this way... when your playing poker and you have a mountain of chips in front of you...lets say you have 1,000,000 in front of you.... it becomes hard to manage with all those small chips... so you trade in all your small chips for big ones so its easier to play.. you dont have to put out a mountain of chips when you bet or go all in... but the good part is when you trade in your chips, you still have 1,000,000 in front of you just a smaller pile. or in our case 1,000,000 dinar.... so i hope this simplify's this for anyone who doesnt get it..
