Don’t worry: your Bitcoin will always make it to your wallet.
There may be times when the Bitcoin you bought does not appear in your wallet right away. This typically happens when a lot of users are buying Bitcoin from our machines at once causing delays for your Bitcoin to be sent out.
There are also times when the block-chain network experiences delays or your wallet provider requires several levels of confirmation that are out of the National Bitcoin ATM’s control. But, don’t worry, your Bitcoin will always make it to your wallet.
If after a couple of hours you STILL don't see your Bitcoin, please check in with our support team at firstname.lastname@example.org. Someone will get back to you with an update on the issue.
