Last time they added BCC on 03.10.2017 so in two months after 01.08.2017 hard fork.
So if they won't add BTG by the New Year I will give up waiting and export my private keys into BTG wallet.

As #1 online wallet and "be your bank" and stuff they should really work faster or post a clearer statement.
Those of us (like me) who doesn't wanna bother with creation of new wallet and paying BTC transfer fee (which isn't low these days) and exporting keys are really wasting selling opportunity.
