Most of the people would be excited by such a news but I'm not. I'm actually against everything that Coinbase does, they might be facilitating access to crypto and trading but from the way I see it, it seems like they are turning into a bank and that's something that shouldn't be found in the bitcoin scene.
Even if they start to offer a variety of services that only banks offer today, we would still have a choice with Bitcoin not to use them. It has several services that many people will still look for and that it is impossible to be offered using only the pure version of Bitcoin and its blockchain.
I believe that coinbase and several companies that were born with Bitcoin will have the ability to erode the entire traditional banks system. But that will not mean ending financial services. means that they will change from what it is today.
