Vertcoin (VTC) is the coin of the Vertcoin enterprise. The coin is featured by a few exchanges and can be mined. The Vertcoin project has developed the “Proof-of-Work” algorithm called "Lyra2RE". Vertcoin was designed to serve as the graphics card mined version of Bitcoin. Therefore, one of the team’s goals is to make the mining process more affordable. Recently, the team decided to release updates on a quarterly basis instead of monthly updates.
Einsteinium (EMC2) coin was released in 2014. It is mineable and can be traded. You can also buy it in exchange for other cryptos (the buying option for fiat is not available yet).
Gnosis (GNO), the native token of the Gnosis platform, is based on the Ethereum blockchain. The token is paired with other cryptos on several exchanges.
