Bitcoin Gold is a hard fork of Bitcoin,just like a child-cryptocurrency of Bitcoin which permits easy access to buy and sell BTC without having to learn much about cryptocurrency trading. This platform is however, inactive for quite some time now and majorly trying to access your email and user password seems to always fail in attempt to do so.
In addition,the hack happened at the time where it was trying to decentralized the security of the platform which actually resulted in a loss of 51% attack leading to the loss of information. Bitcoin Gold was also unable to gain 50% control after the hack of the computing power on the platform. Therefore, there's definitely no much to say about this platform because those important features has been Lost to hackers and I consider this exchange a risky platform to register for now or even make deposit.
