Even if coinbase is not compromised, you should not use it.
Their lack of customer support is disgraceful and makes the experience on their site complete shit.
Coinbase is useful for a few reasons, though. For one thing, zero fees to trade on GDAX (as long as you use limit orders). For another, FDIC insurance on your USD holdings when you're waiting out a correction or bear market. They are tightly regulated and compliant, so assuming a strong password and TOTP 2FA token, I feel comfortable leaving large amounts of USD there.
This all assumes that you pay your taxes and you're okay with verifying your identity. Their KYC procedure is not what I'd call "lax" and it can be difficult if you don't have a smartphone with a good camera. They basically force you to use the mobile app or your computer's webcam.
