Prices can fluctuate heavily, which is why a sell order must be completed within 60 minutes. If the coins don't arrive in this timeframe, the order will be cancelled. You’ll now need to open a new sell order.
Have the coins arrived after the order has already been cancelled? Please contact our support so they can return the coins to you.
Please note: we recommend against sending coins from an exchange since transaction waiting times can often exceed 60 minutes.
