i'm working in forex (foreign exchange). If u have taiwan dollar, when u reach Singapore then only u buy SG dollar. Same like in Malaysia, only change taiwan dollar to Malaysia ringgit, when u reach malaysia.
Please be aware that the more u changing ur currency, the more u will lose, as the bank will earn more.原帖地址: 背包客栈自助游论坛 http://www.bbkz.com/forum/showthread.php?p=2833075
U have taiwan dollar, but u change it to Us dollar before coming to malaysia.
(u lose, bank earn)
Then after reach Malaysia, U need Malaysia Ringgit, thus u change again by using US dollar
(u lose again, bank earn more)
