Coinbase can disable your withdrawal/sending ability at any time on a whim.
Their support is email-only and has a backlog of months. Try taking a look at /r/coinbase for examples.
There are some very good reasons to put your crypto somewhere you control. I am in the process of moving everything I had off of Coinbase after they silently disabled my send/sell ability, but not purchase/receive, without ever providing a reason. Others were not so lucky as I was for them to reply to my support ticket after only 6 weeks of this status. None of their FAQs or support emails acknowledged the exact problem correctly or plausibly answered any of my questions as to why.
