Please note that our company does not withdraw funds to Bitcoin cash (BCH) wallets which use old format received from the parent cryptocurrency Bitcoin (BTC). Thus, in order to receive funds you need to convert old format of your wallet into a new one. There are several converters for this but we recommend https://cashaddr.bitcoincash.org/. After this procedure withdrawal of funds from our company to your BCH wallet will be available.
