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.
At this rate we are going to get an innumerable amount of forks I was not aware of this fork but to be honest I do not care, bitcoin could not change its algorithm without declaring a frontal war against the miners so that is the last option and will only be used if the miners go with the segwit2x fork, but Im curious who is supporting this fork?
