Chapter 4

Sending Bitcoin

A Bitcoin transaction starts in a wallet, but it does not become final the moment you click send. The network still has to validate it, relay it, and eventually include it in a mined block.

That is why wallets show different states like pending, confirmed, and confirmed multiple times. Each label reflects where the transaction sits in the path from local intent to shared settlement.

Fees influence how quickly miners notice and include a transaction, especially when block space is busy. A valid transaction can still wait if other pending transactions are paying more per byte.

This sequence is why Bitcoin users learn to separate sending from settling. The transaction feels immediate at the interface layer, but the network treats certainty as something earned over time.
