CCB is a totally unused cryptocurrency. Currently there are no private wallets capable of storing CCB, however the exchanges that can generate CCB wallets (Yobit & Cryptopia) do have a very good track record as both being two of the oldest, popular exchanges, and never having any major breaches in security.
With that said however, all transactions relative to CCB outside of seuva’s systems are at your own risk. Please be cautious. In the meantime, if you prefer to wait until May 2019 seuva is soon to begin developing cold wallet storage for CCB, as well as online access seuva storage that holds funds in either cold and soft wallets, up to the user’s discretion.
