Back in 2017 when Bitcoin Cash came into light, it was given BCH ticker on most exchanges. In 2018, Bitcoin Cash Satoshi Vision was born and some exchanges changed Bitcoin Cash ticker from BCH to BCHABC. Bitcoin Cash Satoshi Vision was simply called BSV.
In 2019, Binance delisted BSV but did not rename the Bitcoin Cash back to BCH even though most exchanges continued to call BCH as BCH and not BCHABC. Due to people bugging Binance at all times, Binance has updated the ticker of BCHABC to BCH.
* Deposits, withdrawals, account transfers of BCHABC and also trading in the BCHABC/BTC, BCHABC/USDT, BCHABC/USDC, BCHABC/TUSD, BCHABC/PAX, BCHABC/BUSD trading pairs will be suspended at 2019/11/28 02:00 AM (UTC). All open orders in these trading pairs will be canceled.
* Binance will credit all users with BCH based on a snapshot of their BCHABC balances at 2019/11/28 04:00 AM (UTC) at a ratio of 1 BCHABC = 1 BCH.
* Binance will then open trading for BCH/BTC, BCH/USDT, BCH/USDC, BCH/TUSD, BCH/PAX and BCH/BUSD at 2019/11/28 10:00 AM (UTC), while at the same time removing all previous BCHABC trading pairs.
All users that deposit BCHABC during the above ticker change process will be credited with BCH in their accounts.
