Confirmation
A confirmation means a transaction has been included in a block. Each subsequent confirmation strengthens its finality.

Why It Matters
Pools, exchanges, and payment services may wait for several confirmations before treating a deposit as valid.
What to Watch For
An unconfirmed transaction can stay pending if its fees are too low during a busy period. Bitcoin miners usually include the highest-paying transactions first, which is why low fees wait longer.
