Bitcoin Gold? What the heck is that? I've never heard of it before. Btw, on marketcoincap, BTG is assigned to Bitgem.
Is there a way to mine BTG ? Is there a special wallet on Windows?
From what I've read, they are going to change the Algo to Equihash, which is supposedly friendly to GPU and even CPU mining. But you won't be able to mine it until after the fork.
