USD1 = 16,500 Vietnamese Dong, which literally makes me a millionaire in during my Vietnam visit (well, who isn’t?)… it’s actually quite a pain though, for foreign travellers who are slow in counting lol.
Vietnamese Dong (đồng), if not mistaken, is the second least valued currency behind Zimbabwean dollars. The face value of Dongs started rising since late 80s because of inflation; in 1985 the largest banknote was 500, but now 500,000.
Despite the high inflation rate, Vietnam’s economic growth is quite decent over the time span… most Vietnamese are probably living better now as compared to a decade or two ago.
