On October 25th, the Bitcoin blockchain is set to hard fork and create a new cryptocurrency called Bitcoin Gold (BTG). Existing private keys holding a Bitcoin balance at that time will be credited with the same amount of Bitcoin Gold on November 1st, similar to how they received Bitcoin Cash at the beginning of August. A wallet for Bitcoin Gold will not be available at the same time, however, and it appears it may be weeks before holders will be able to use the new coins.
