Hello,
don´t you know if someone from EU can become a customer of huobi . com marketplace and trade there as well? I just visited their pages but see only a spilled pieces of tea

... and I cant find if they ever have an english version of their pages? I doubt about it. But perhaps somebody knows more?
Yes. Foreigner can also open an account in Huobi. In their KYC verification page, passport ID can be used.
However, if you want to deposit CNY into Huobi, you might need to have a bank account in China.
