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.

Soarcoin is an Ethereum-based token that was created by a company in Singapore called Soar Labs. Soarcoin's total supply has already been released. Since it can not be mined, the price of the SOAR token will be completely dependent on supply and demand. The company's marketing materials place an emphasis on low transaction fees, privacy, and fraud protection, but it does not appear to offer any noticeable benefits to other cryptocurrencies. Soar Labs also has plans to create a cryptocurrency exchange called Soar Ex, that will focus on the Southeast Asian market.

Peercoin is the first Proof-of-Stake (PoS) cryptocurrency. It was created in 2012 and is one of the oldest and most reliable cryptocurrency networks in the crypto sector. The protocol was developed by Sunny King and Scott Nadel, both of whom are anonymous. Sunny King also created Primecoin and VEE.
Peercoin’s PoS consensus mechanism is now widely used in the blockchain space, and allows every network participant to be both a miner or an owner. The project is focused on creating a cryptocurrency platform that will be stable, secure, energy efficient, and distributed fairly.
