We will need to wait for the announcements for the bigger exchanges, but I think not many will support bitcoin gold.
I am curious to see which wallets, if any, will support bitcoin gold.
Bitcoin Gold is a scam. Core's way of trying to create more "dividends". Looks like may have been attempted under Blockstream management. The website for bitcoin gold was registered anonymously and the only contributors to the GitHub are Core/Blockstream people.
