When you receive Bitcoin, it is not immediately considered fully final. The network needs time to confirm the transaction before it can be safely spent again.
This delay is a core part of how Bitcoin maintains security.
Blocks are created approximately every 10 minutes
Bitcoin transactions are grouped into blocks.
On average, a new block is added to the blockchain every 10 minutes. This timing is not fixed—it can be shorter or longer depending on network conditions—but 10 minutes is the expected average.
Each new block adds a confirmation to your transaction.

Confirmations establish ownership
When a transaction is first broadcast, it is visible to the network but not yet fully settled.
Once it is included in a block, it receives its first confirmation. With each additional block added afterward, the number of confirmations increases.
More confirmations mean stronger agreement across the network that the transaction is valid and irreversible.
Waiting reduces the risk of reversal
Before a transaction is confirmed, there is a small risk that it could be replaced or invalidated.
As confirmations increase, this risk drops significantly. After around six confirmations (roughly one hour), reversing a transaction becomes extremely difficult in practice.
This level of finality is one of the key differences between Bitcoin and traditional payment syste
