Bitcoin Gold? What the heck is that? I've never heard of it before. Btw, on marketcoincap, BTG is assigned to Bitgem.
Bitcoin Gold is a fork of bitcoin just like Bitcoin Cash. One of the notable changes is that they have changed algorithm to Equihash which makes it asic resistance and its a memory intensive algorithm. The idea is to bring back GPU mining plus some other changes.
Sorry, I'd like to know, have this fork taken place or it's planning to, cause I have not heard anything of such fork coming up, except now and in this thread.
