CoinExchange.io UPDATE - The kB3/BTC Market is now updated and opened for trading.  The B3/BTC Market will remain deactivated(maintenance mode) until they adjust their B3 trading scripts. This means that if you have coins in your B3/BTC wallet, you will not be able to move your coins yet. The original 3/14/18 mandatory deadline will be moved back to a later date (not yet determined).

Thanks for your patience.
