I ordered bitcoins, when will they arrive in my wallet?
Your bank account needs to be verified once for your first purchase. The bitcoins will be reserved for you immediately, but they will only be sent when the verification process has been completed. See also: verification
When your bank account is verified and you see a bitcoin transaction-ID on our transaction overview, it means the bitcoins have been sent to your wallet. You should receive your bitcoins (almost) immediately. During peak times we group transactions together, it could take a few minutes before bitcoins are sent. In addition, our fraud detection system checks on unusual characteristics in transactions. When a transaction is classified as “highly unusual”, it will be reviewed manually. This may delay the processing of the transaction or result in the request of additional information.
It could be that bitcoins do not immediately appear in your wallet, because:
You use a wallet on an external website that requires confirmations (by the Bitcoin network).
Confirmations indicate that the transaction has been recorded in the blockchain (the Bitcoin database). Miners who contribute to the network generally will, on average, find a block every 10 minutes which will confirm your transaction automatically. More confirmations mean a more definitive transaction. Some wallets only credit bitcoins when the transaction has 6 confirmations. If you still don’t see bitcoins in your wallet after 6 confirmations we advise you to contact the website.
You use a local wallet on your computer or phone, but it is busy synchronizing or a network error occurred (for example Bitcoin Core / Bitcoin QT).
If your wallet is still synchronizing it means that the blockchain is not yet completely loaded. Your transaction will be placed at the end of the blockchain, which is why the purchased bitcoins will only appear when the blockchain has been fully downloaded. It could also be that your wallet cannot make a connection to the network, because of a firewall for example.
Should this be the case, and you need your bitcoins urgently, you could choose to import your "wallet.dat" file to a web-wallet. At blockchain.info this option is provided, for example.
You use Multibit and the transaction does not appear.
Multibit sometimes does not see incoming transactions. You can fix this by clicking on the menu bar on "Tools" and then "Reset Blockchain and Transactions". Click here for more detailed instructions.
