The Bitcoin Cash (BCH) network is experiencing a planned protocol change via a hard fork on November 15, 2018.
While non-backward-compatible hard forks allow for rapid protocol innovation, they also carry a risk of creating a permanent split in a network. It is possible that Bitcoin Cash will experience this kind of split. This would create two versions of the Bitcoin Cash chain, resulting in disruptions for Bitcoin Cash payments.
To minimize risks to merchants and BCH users during the hard fork, BitPay has temporarily paused Bitcoin Cash payment processing until we determine that customers can pay safely. You can continue to use Bitcoin (BTC) to complete your payment until we restore Bitcoin Cash as a payment option.
