Why does BTC transaction take long time?

There are a number of reasons why transaction confirmation delays may occur:

1. Network congestion is a significant contributing factor. The number of BTC transactions has increased significantly in recent years, leading to an increase in the number of transactions waiting for confirmation. This can result in a slower processing speed for transactions.
2. Fees: The Bitcoin network is maintained by miners who have the authority to determine which transactions are processed first. A higher fee per byte of a transaction increases its priority and speed of confirmation.
3. If your bitcoin transaction is delayed, please be assured that this is not cause for concern. On average, transactions may take up to several hours to process, and in rare cases, up to several days. Once the transaction has been successfully completed, the funds will be delivered to the recipient or returned to your wallet.
