There is a very good chance that current exchanges will delist BCC in order to avoid legal trouble and all remaining Coins will be worth $0

Although selling at $18 in other exchanges., technically, the coins are already at 0 within bitconnect exchange but many deadlocked at $150 inside bitconnect X. The Cease and Desist order as given one of the main causes of closing London Centralized Exchange also includes Bitconnect X as shown on page 5:
