The "Bitcoin Gold" hard fork currently does not seem to be a viable fork - since they have not given any information about the fork on their website (btcgpu.org) and have no supported wallets yet. If there are no wallets that support it, we shall not be able to make "Bitcoin Gold" available for withdrawals. If however, there is wallet support for "Bitcoin Gold" before the hard fork date and the block number for the fork is announced in advance, we shall make it available for withdrawal.
They've made site updates recently
The Bitcoin Gold (BTG) initial coin distribution method is exactly the same as that used by Bitcoin Cash (BCH). All Bitcoin holders who possess BTC private keys on October 25 (block 491 407) will receive Bitcoin Gold on the rate of 1 BTC = 1 BTG (If you have 20 BTC you will receive 20 BTG). You need to control BTC private keys in order to make Bitcoin Gold transactions.
