UPDATE 20/Feb/2014 02:24 PST:
USD Deposits Temporarily Disabled

Unfortunately, we've reached the limit of our US bank's capacity to deal with the volume on our account. Many USD withdrawals have been delayed beyond a limit we can accept, and it reflects poorly on our service. Rather than continue to disappoint, we've decided to suspend USD deposits until a more robust banking partner is acquired. In the meantime, USD withdrawals and trading will continue to be available, though we strongly encourage USD traders to shift to our EUR pairs. Most major banks will allow you to send EUR even if your account only holds USD.

USD Deposits Temporarily Suspended

USD deposits are suspended until April 1st, 2014. We encourage you to trade the EUR pairs in the meantime. Most major banks will allow you to send EUR, even if you only hold a USD balance.

USD withdrawals are still being processed
