What causes delays in Bitcoin transactions?

Delays in Bitcoin transactions are often caused by network congestion, where the volume of transactions exceeds the network’s processing ability. This congestion leads to a backlog of unconfirmed transactions.

Another factor is the block size limit of 1 MB, which restricts the number of transactions that can be included in each block. When too many transactions are waiting, those with lower fees may experience longer delays as miners prioritize higher-fee transactions.

Additionally, the need for multiple confirmations to ensure transaction security can add to the delay. These factors together can cause Bitcoin transactions to take longer, especially during periods of high activity.
