Putting Coinbase and MEW in the same category is pretty misleading.. Coinbase is an exchange, completely different from what MEW is. The fact that the user doesn't control the private keys on an exchange means it really isn't a wallet at all, it's just an account.

There's also zero emphasis on security in this article, which is a massive red flag for any readers. Security isn't an afterthought in crypto, it's a fundamental pillar of the technology and ignoring it means you don't even know what crypto is about and you definitely shouldn't be putting money into it.
