Coinbase adds support for ethereumrazvanul05 (31)in #ethereum • 9 years ago https://blog.coinbase.com/2016/07/21/coinbase-adds-support-for-ethereum/
This is big news for Eth. You could previously buy it on GDAX (run by Coinbase). But, Coinbase's millions of users being able to buy directly on Coinbase with debit/credit cards will definitely accelerate adoption.
Also having a mobile app to trade will help the community to grow faster.
