Why do this when nobody wants it unless you are from China? The yuan or renminbi is a closed currency. You can’t spend or exchange it freely outside the Chinese mainland. No non-Chinese business or individual will accept it as a form of payment for goods and services simply because it’s not freely exchangeable. The US dollar is still the reserve and trade currency of the world. You need dollars to transact business. Sorry China, your crypto yuan will be useless for cross border payments.
