Within three hours we will be enabling ETC deposits and withdrawals. At this time the ETC wallets will be enabled for all users and ETH balances from 13:20:40 UTC 20/07/2016 will be credited to users’ ETC wallets. Due to their technical similarities ETH and ETC can share deposit addresses, so generating new deposit addresses will create an address used by both. Upon receiving the deposit we will correctly handle and process the deposit and credit the account with the corresponding ETC or ETH amount.
We are still in the process of preparing ETC trading, however we plan to be live soon after deposits/withdrawals are enabled.
ETC already reflecting in the balance. Waiting for the markets!!
