CubToken is a blockchain-based “ERC20” asset with similar functionality to bitcoin, ether, and bitcoin cash: it can hold value and be sent and received. The main difference between CubToken and other cryptocurrencies is that CubToken was deployed and hosted on the Ethereum blockchain, considering that bitcoin and bitcoin cash is the native currencies of their respective blockchains. CubTokens are stored and sent using Ethereum addresses and transactions and it uses something called gas to cover transaction fees.
