UPDATE 10 January 2022: The Circle-company still seems to be very active, but we can't seem to find any information on its cryptocurrency wallet. Accordingly, we believe that the company has dropped the Circle Bitcoin Wallet from its product offering. Until further notice, we have removed it from our Cryptocurrency Wallet List.
To find an active cryptocurrency wallet, please refer to our Cryptocurrency Wallet List.
A more detailed review of Circle Bitcoin Wallet will follow here shortly!
