Here's another story: Long ago I tried to withdraw my BTC, but after clicking the withdrawal button the browser tab was stuck waiting for the HTTP response. So after a while I opened a second tab and tried to withdraw again. Both withdrawals went through and I ended up with a negative BTC balance on Coinbase. I sent one of the transactions back so that my balance ends up at zero again.

Oh dear... this sounds like another Mt. Gox waiting to happen. In what world will this not be exploited sooner or later?

I'm (pretty) sure this is a result of them using MongoDB. A friend of mine also accomplished a double sell (BTC -> USD, -1x credit on the BTC but +2x on the USD), he ended up keeping it and never hearing from Coinbase.
