The worthless Forkcoin known as "Bitcoin Gold" is even more worthless having been hit by double spending and 51% attacks demonstrating that its deviant blockchain lacks sufficient interest and value to attract sufficient mining activity. Much like the Roger Ver-ified "Bitcoin Cash" Forkcoin, "Bitcoin Gold" was split from the Bitcoin Blockchain via hardfork by a marginal crew with odd politics and like "Bitcoin Cash" failed to attract sufficient serious interest to matter.
The hill on which the "Bitcoin Gold" crew chose to die was changing the mining algorithm to a GPU mining friendly memory hard algorithm of recent publication dubbed "equihash" leaving their blockchain's security to the mercy of altcoin miners with GPU farms and no particular loyalty to any of the non-Bitcoin blockchains they mine. The meteorological risk of circumstances aligning to make these attacks the natural, economically rational choice for miners looms over every purported "cryptocurrency" blockchain that fails to attract sufficient value to actually be Bitcoin.
