Being originally based on the Ethereum blockchain, the Enigma (ENG) token has moved to the network’s own mainnet in 2019. As an ERC-20 token, it still can be traded on a number of exchanges against major crypto coins.
Skycoin (SKY) is the native coin of the Skycoin Internet platform. You’ll be able to buy the coin on the project’s website, as well as to trade it against other cryptos on a number of exchanges.
