This is just an FYI for anyone thinking about using Coinbase for their trades. Coinbase makes you periodically re-verify your identity. This process used to be manual. It is 100% automated now and it rarely works (look at Coinbase community forums for more on this). I've had a support ticket open regarding this issue for 3 weeks now and the only response I've gotten so far is "As we experience rapid growth, we are also experiencing a high volume of support requests and we regret not being able to answer your inquiry in a reasonable amount of time." I don't have any serious money tied up in Coinbase, but if i did I would be freaking the fuck out right now with this appalling support service.
