Bitcoin Gold (BTG) is a cryptocurrency established during a Bitcoin hard fork in 2017. The reason behind the origin of the Bitcoin Gold coin is an attempt to make a more decentralized version of the original cryptocurrency. The BTG crypto uses the PoW consensus algorithm, just like BTC does. However, Bitcoin Gold is powered by the Equilash hashing algorithm instead of SHA-256, to prevent the situation of several ASIC mining pools centralizing the crypto.
The price of BTG showed its peak shortly after the creation of the coin, reaching the 474 dollars per coin mark, but the Bitcoin Gold chart shows a gradual and stable decline over the course of 2018 after the peak. Still, the Bitcoin Gold market cap allows it to stay in the top-30 cryptocurrencies in terms of market cap with over 217 million dollars at press time.
