Re: cny vs e-cny
CNY is backed by the government so it's safe as long as everybody believe their numbers.
I do not think the chinese government is to be trusted, most recently we've seen chinese companies voluntarily pulling out of US stock market when faced with the chance of being audited (before they were exempted because of ccp pressure) and this is one of the several red flags about their economy.
Anyways eveybody is free to gamble.
