Confirmed exchanges that will support selling of bitcoin gold?

[mls151]

First off, I know the BTG mainnet isn't live (yet).

Also, My BTC were in Electrum the whole time, as i understand some exchanges only give you futures if your BTC were stored with them before the BTG fork.
So I'm looking for exchanges who confirmed they will trade BTG ( regardless of having BTC in their own exchange/wallet) Thanks.
