The official Bitcoin Confidential ticker is “BC” and trades under that name on all the exchanges where it has been listed. The designation “BITC” is for CryptoCompare only.
Bitcoin Confidential (BC) is a Proof of Stake cryptocurrency focused on confidential transactions through the use of Ring Confidential signatures (RingCT). Since confidential transactions have been mandatory since block zero, it is impossible to link coins to historical transactions. As such, Bitcoin Confidential coins are fully fungible and always equivalent in terms of value.
