An unconfirmed transaction means that the transaction has not yet been included in a block and is thus uncompleted. Common reasons for unconfirmed transactions are:
- You have just made the transfer. The Bitcoin network needs at least 10 minutes, on average, to include the transaction in a block;
- The blockchain fee is too low or absent. The lower the blockchain fee, the lower your transaction's priority in the Bitcoin network. Therefore, the confirmation will take longer;
- The Bitcoin network is overloaded. Due to its limited capacity, the network simply cannot process transactions fast enough, especially during high transaction periods.
