If you sent BCH to a BTC address (or vice versa) by mistake, this is considered as a cross-chain deposit. A cross-chain deposit occurs when tokens are sent from one cryptocurrency blockchain to another. Wallets for one blockchain token cannot support tokens from another blockchain. This means that, for example, sending Bitcoin Cash to a Bitcoin wallet would result in the loss of the Bitcoin Cash.
If you sent your Bitcoin Cash to your Coins.ph BTC or ETH address by mistake and wish to have it recovered, please refer to our cross-chain deposit recovery policy.
