A transaction confirmation delay may have several reasons: 1. Network Congestion: In recent years, the number of BTC transactions has increased significantly, resulting in an increase in the number of transactions awaiting confirmation. This may slow down the speed of transaction processing. 2. Fee: The Bitcoin network is maintained by miners who choose which transactions to process first. A high transaction byte fee increases its priority and confirmation speed. If your Bitcoin transaction is delayed, don't worry. On average, transactions can "freeze" for several hours, sometimes even for several days. Ultimately, the funds will be successfully delivered to the recipient or returned to your wallet.
