Bitcoin Gold (BTG) is a cryptocurrency that began in 2017 as a hard fork of the Bitcoin blockchain. BTG was created to reduce the monopolizing power of dedicated ASIC mining operations within the original Bitcoin network. Bitcoin Gold mining can be done by anyone with a standard computer and provides greater decentralization to the system. The hard fork that created BTG was meant to combat the disproportionate influence and competitive advantage of professional miners.

Bitcoin Cash SV is a cryptocurrency that was created as a result of a hard fork of the Bitcoin Cash blockchain that occurred on November 15, 2018. The central issue that led to the hard fork of Bitcoin Cash was a debate among prominent members of the Bitcoin Cash community regarding block size. A larger block size can improve transaction times, but also lead to greater network centralization. Roger Ver, an influential cryptocurrency advocate, was one of the central figures in favor of keeping the smaller 32 MB block size, while Craig Wright, the chief scientist at nChain, favored a larger 128 MB block size. The division between these two factions led to the hard fork that created Bitcoin Cash ABC and Bitcoin Cash SV.
