Re: Coinbase. :-(

So whats the verdict ? Why did they cancel the orders and don't allow buying BTC ? I still don't get it, didn't they provide an explanation on how to fix this ?

The verdict is that they cancelled the orders for no reason and refunded the money after holding it for a week.

I am pretty sure they didn't cancel those orders to profit from the exchange rate difference. There must be some kind of deeper reason behind this?

I can't say why they cancelled the order, but I can say that every verification was completed and I don't think anything could have been done differently that would have made this order successful.

The problem here will be that they work with a "zero mistake" policy. So even if they canceled it on accident and it was indeed a legit order (which it looks to be), they will never admit that.
