This site is a scam!
I made a transaction on 2017-08-02 16:30:11 (Block 478735), for a total of 1.14 BTC.
And my last transaction was yesterday, reducing my BTC to 1.12 BTC.
Any address I put on the transaction from block 478735, does not show the reward. If I enter the address of the transaction yesterday, it returns the value 1.12 BTC to recover in BCD.
Did you check Coinomi? You can also contact the dev on Twitter then let him know that you can't find a real wallet to use to claim BCD coins.
