Thanks for sharing that. Very useful.
So, in a line... You can sell BCC at ViaBTC but you can't withdraw your bitcoins!
they want 6 or 20 bch confirmations before you can pull anything you've traded it for off. i'm not sure which figure. seems fair enough to me.
Hmm very twisted logic. If BCH confirmations are the problem then BCH deposits should be limited not bitcoin withdraws. Limiting bitcoin withdrawals means this exchange is running fractional reserve on bitcoin! It is very dangerous to keep your bitcoins there!
Bitcoin withdrawals are limited by the People's Republic of China and its regs not the blockchain, you'll probably have to provide verification for your account and then wait while they check who you are and consider letting your money out of China.
