The Chinese Yuan is one of the major currencies in the world. Still, there are a limited number of online casinos that will accept it. Chinese players will find it very difficult because the Chinese have banned both online and standard casinos. Those who want to play using the Chinese Yuan are limited to the brick-and-mortar casinos located in Macau, part of China but with different regulations to the rest of the country.
The Chinese Renminbi (RMB), often referred to as the Chinese Yuan is the official currency in China and an unofficial currency of some of its neighbouring countries. The currency is issued by the Central Bank of China and came into circulation in its current form back in 1948.
The RMB was until 2005 pegged to the US-Dollar but is nowadays a free floating currency. It's one of the largest currencies in the world and an appreciated currency on several online gambling casino sites.
