A little birdie told me that Coinbase does not have it together in the back-office as I would have hoped and not all errors are in Coinbase's favor...by a long-shot! I can only imagine what a mad-house it must be at this time.
You mean like the time where they sold me some bitcoins, and their back end forgot to initiate an ACH to pay for it, and even after I opened up a ticket with support they never did end up charging me for them?
Something along those lines. I encouraged the little birdie to do the right thing so that the sky Gods would admit it to Birdie Heaven. Birdie said it'll wait for action from the other end.
My guess is that Coinbase is making so fuckin much money now that they don't even give a shit unless back-end errors are systematic and thus costing them wads of cash in a uncomfortably large batch sizes.
