What currency is used in Taiwan?
New Taiwan dollar
It is relatively easy for the government to disseminate these denominations through various government bodies that do official business with the citizens, such as the post office, the tax authority, or state owned banks. There is also a conspiracy theory against the Democratic Progressive Party, the ruling party at the time the two denominations were issued. The conspiracy states that putting Chiang Kai-shek on a rarely used banknote would "practically" remove him from the currency, while "nominally" including him on the currency would not upset supporters on the other side of the political spectrum that much (the Pan-Blue Coalition).
