When you initiate a cryptocurrency transaction, you expect it to be promptly confirmed and added to the blockchain. However, there can be instances where your transaction experiences delays in confirmation.
Network Congestion:
One of the most common reasons for transaction delays is network congestion. When the network is experiencing high transaction volumes, miners have a larger pool of transactions to process. As a result, it may take more time for your transaction to be included in a block and confirmed.
During periods of intense network activity — such as market volatility or popular events — these delays are more likely to occur.
Insufficient Transaction Fees:
Transaction fees incentivize miners to prioritize certain transactions. If the fee attached to your transaction is too low, miners may process other transactions first. This can result in your transaction waiting longer to be confirmed.
To avoid delays, it’s important to set an appropriate fee based on current network conditions.
Replace-by-Fee (RBF)
If your Bitcoin transaction is stuck due to a low fee, Replace-by-Fee (RBF) allows you to resend the same transaction with a higher fee to speed up confirmation.
This option can be particularly useful during times of high network congestion.

Network Upgrades or Forks
During network upgrades or forks (for example, a hard fork or software update), transaction processing may temporarily slow down or pause. These events can cause short-term confirmation delays as nodes and miners update their systems.
Note: Blockchain.com has a Customize Fee option that allows users to specify a custom fee and this can come in handy to help ensure your transaction confirms quickly during periods of congestion. We recommend this option to experienced users with an understanding of transaction fees only.
