Coinbase has announced to list CARDANO(ADA) BASIC ATTENTION COIN(BAT),0x protocol, ZEC and stellar world as they want to clear to whole world about their transparency. Unlike the ongoing process of adding Ethereum Classic which is very simiilar to ethereum there is no chance of these five coins become tradeable loke others too.
looking forward, we should expect that they will make similar announcements about exploring the addition of multiple assets.manycof these assets may become available everywhere, while others may only be supported in specific jurisdictions.
