That is a good Question. It seems that Exodus have expressed their support for BitcoinCash however don't support BitcoinGold. Hence,why you would need to claim your BitcoinGold via your Private Key. This should be done via BitcoinGold Client, which should become available soon. However, i'm keeping my BitcoinGold, cause I'm not going to entrust BitcoinGold Developer by using my Private Key online anytime soon. You'll mostly likely have to wait 1 or 2 Months
