Starting August 24th 2017 Japan time, BCH withdrawal service will be available for all QUOINEX users.
BCH incoming transactions generally take a longer time than its BTC counterpart to be broadcast on the blockchain. It can take a while for your receiving address to reflect the change.
For more details regarding withdrawal processing schedule, check out QUOINEX Help Center section for crypto withdrawals here. If what you are looking for cannot be found there, do not hesitate to contact us at email@example.com.
Remember, BCH trading is available on QUOINEX in three spot trading pairs, BCHJPY, BCHUSD, and BCHSGD. We look forward to see you trade with us!
