Question: What is "confirmation" of Bitcoin transaction? Why is it needed?
The “confirmation” must be made for Bitcoin transactions, to prevent “double-spending” of the currency.
The Confirmation will be made within the network, and once your transaction gets confirmed, it will be included in one block and more.
Bitcoin transactions are made instantly, but can take up to 90 minutes. The average time is about 10 minutes.
More fees you pay for the community, quicker the transactions will be made.
What is Double-Spending?
No one can spend the same Bitcoin twice just like any other currencies.
To make sure that this won’t happen, Bitcoin market requires this “Confirmation”.
Each transaction will be buried under blocks, and it is up to you when the payment is confirmed.
