How long does it take to send Bitcoin?
Sending bitcoin to an email address happens almost instantaneously.
Small amounts of bitcoin (e.g. less than 0.5 BTC) are typically sent within a few seconds.
Larger transactions take longer to process since the Bitcoins have to be retrieved from a secure cold storage system. This is done in batches twice per weekday. These will be listed as "Pending" in your transactions list. It is possible to cancel pending transactions before they are sent (click on the transaction to find the cancel button).
Once the transaction has been sent, it will take approximately an hour for the Bitcoin network to confirm the transaction.
