Understanding Bitcoin Confirmations

What happens during the Bitcoin mining process is, a new block is produced and added to the Blockchain. Based on the already set bitcoin protocol, the creation and addition of a block takes roughly ten (10) minutes.

What that tells us is, when you send Bitcoin to any wallet, the transaction will remain 'unconfirmed' until the next block is created. Your transaction is included and verified as that block is created. 

Therefore, your transaction will have one confirmation. When another block is created, your transaction is reconfirmed by the Bitcoin network. 

The miner fee attached to a transaction usually determines the speed of confirmation. There is a recommended miner fee on every Bitcoin transaction. A lower than the recommended fee will make the transaction speed slow.
