I think craig wright got the idea when cz mentioned a couple of weeks ago he wanted to reverse the blockchain so to get back those 7,000 btc stolen from his exchange. It was something nobody wanted to happen or could even be achieved in some discussions.
Csw at it again with the absurd and unknown to garner even more attention away from bitcoin and its blockchain.

That is probably what is happening here. CW is a man of publicity and attention and he is open to any idea to further his own sick dramatics. The man has the capacity to entertain absurd idea even for the sake of being talked about. As to that "Reverse Bitcoin Hardfork" called GoldCoin I think they can do whatever they wish for that blockchain and we in bitcoin will not be affected. Seems people these days are disconnected with realities and workable technologies.
