If your still waiting for bitcoin you bought at one of our ATMs:
The more confirmations a transaction has, the more 'hard' it is. Some wallets and websites require more than 1 confirmation in order to confirm that they have received your funds. If you notice that at blockchain.info your address has received the bitcoin, and that you have at least one confirmation, but your wallet still doesn't show it, then its likely that your wallet requires 3 or 6 confirmations.
If trying to withdraw cash from one of our ATMs:
In general, when selling Bitcoin your cash will be available after 1 network confirmation (On average 10 minutes, sometimes up to 1 hour). You will receive a text message notifying you when your cash is available for pickup, along with a redemption code. For small amounts, you may receive your cash instantly upon sending the Bitcoin to the specified address within 120 seconds of the QR code appearing on the screen.
