However removing BCC balances from their platform doesn`t quite explain where everyone`s BCC have gone. They must be somewhere ?
it didn't go anywhere, the name changed from BCC into something else (BCHABC)! and it is still the same altcoin and you still should have the same balance. if it is otherwise then contact support, it may be a bug with you alone. although it is unlikely. make sure you actually had some bitcoin-cash in your binance wallet first and if you are sure you had some then it should now be called BCHABC.
