If you are unsure whether your bitcoin address has received funds and/or do not have your bitcoin wallet at hand you can still check by using a Blockchain Explorer, as all bitcoin addresses are publicly visible on the bitcoin blockchain you can look them up if you are aware of the address or the transaction id.
If you need support, giving us the transaction id or the bitcoin address will greatly improve the service we can give you, so the more information you give us, the better our answer will be :)
Please see the example below:
- We find the transaction within the Transactions Tab, it already shows us here that our transaction has 0 Confirmations
- Select the Transaction in question, at the top select Show Details
- The Transaction Details will be shown in the following screen, listing all inputs as well as outputs used by this transaction. Clicking on any of the details will show you the address (or transaction when selecting the Hash/Transaction ID) in the BlockExplorer you have specified in the settings.
- We can look up all details of the transaction by searching for any of the details above using an blockchain explorer, such as blockcypher.com or blockr.io
Looking at the transaction using an block explorer you can see that our transaction is received but still unconfirmed by the network, as it has not been mined into an block by an miner yet. The time it can take for the first confirmation to take place depends on the fee that the transaction is giving to the miner. The higher the fee, the higher the likelihood to be included in the upcoming block. See below the transaction displayed by blockcypher.com
The same transaction displayed by blockchain.info
Once your transaction has been mined into an block it will start to build up confirmations as additional blocks are build on top of it, making the block with our transaction stronger. As an unconfirmed transaction in bitcoin can not be deemed safe, most services will require a certain threshold of confirmations before you can use your funds, this is often 3 or 6 confirmations.
Below example of our transaction with 3 confirmations
Once a transaction has received 6 or more confirmations it is considered safe, as it would take too much mining power to undo this transaction than is considered feasible
