From their blog post, Coinbase announced that it was exploring the addition of five cryptocurrencies to its list including Zcash, Cardano, and Stellar Lumens. The exchange also says that they are working with local banks and regulators to make them available in as many jurisdictions as possible.
They made it clear that these assets would require additional exploratory work base on their architecture and they cannot make any guarantee that they will make their way to trading. The blog post stresses that even if Coinbase was to integrate them, the features supported may not be all-encompassing, due to a potential for technical and regulatory constraints. The post stated:
“Our listing process may result in some of these assets being listed solely for customers to buy and sell, without the ability to send or receive using a local wallet. We may also only enable certain ways to interact with these assets through our site, such as supporting only deposits and withdrawals from transparent Zcash addresses.”
To get listed on Coinbase has historically been a bullish signal for any coin in the market because being listed give the crypto community a sense of hope that their favorite crypto is not a scam.
