Bitcoin Gold is famous for being the target of a 51% attack in May 2018. In a 51% attack, the attacker exercises control of more than half of the hashing power of the cryptocurrency. Approximately $18 million in Bitcoin Gold tokens were diverted during the attack.
Bitcoin Gold is sponsored by the Bitcoin Gold Organization, which consists of seven co-founders and additional staff. Bitcoin Gold's mining protocol uses the equihash algorithm in its proof of work. Equihash is designed to rely on computer memory and is supposed to be resistant to the dominance of application-specific integrated circuit technology.
As of October 4, 2018 Bitcoin Gold was the 23rd largest cryptocurrency as ranked by market capitalization according to data on CoinMarketCap. There were 17,269,449 coins in circulation trading at about $25.11 per coin, and it was the 30th most actively traded coin.
