iriani like money paper bleach the color and stuff and then resell the paper over and over again i wont go indepth but im sure one piece of money paper is worth far and beyond this shit currency, therefore the paper is wayyy more costy than the currency itself, i did this method myself and gotten away with almots 4k grand i only stopped it due to legal reasons don't wanna be caught.

actually works ask any banker or mathmatetician.
