Where is the bitcoin gold wallet?
I'd say it's a poor work by the team. I don't think there is an official wallet but wallet like coinomi and frewallet (bitcoingold) are supporting it.
Yes, even it didn't got the same responsibility same as that of the past bitcoin cash fork. Maybe soon it gets updates and more wallet supporting bitcoin gold will be generated. If this has gained more market value now this could have hot more importance. Now once again the price of bitcoin has started to move forward, so possibly once again the price of bitcoin gold might decrease.
