The issue of unconfirmed transactions came to a head in December during the peak of the cryptocurrency craze. Due to the double whammy of overloaded exchanges and constant DDoS attacks, a whopping number of , Bitcoin transactions remained unconfirmed for over a day. If a transaction remains unconfirmed for too long, it can be eventually "forgotten" by most nodes on the Bitcoin network if no one rebroadcasts the transaction. This happens due to node restarts, mempool expiry times, or mempool eviction because the minimum mempool fee has increased. This process typically takes a few days (usually 3).
Transaction bitcoin unconfirmedHow to Fix Bitcoin Unconfirmed Transactions [Reverse]
Bitcoin is said to be an unconfirmed transaction when a particular transaction over-stays the entire BTC block time, or without being confirmed after 2 hours you have sent it out.
However, when this happens you will need to cancel the bitcoin transaction entirely, and right here, am to show you how to do it.
Before we continue, i will like you to know that the required number of confirmations for every bitcoin transaction to be fully confirmed is mostly 3 or a little bit above in total. Just check the blockchain unconfirmed bitcoin transactions chart to see if the transaction is stuck already. There are so many things that can actually keep your Bitcoin transaction for more than 24 hours even, but these ones below are the most popularly known reasons:.

To do double spending, you will have to make a new transaction to yourself with the exact equal amount of the original transaction that got stuck in the blockchain confirmation. This time, make sure that the transaction fee is high enough to get the transaction confirmed by the miners.
You may need another crypto wallet that allows such feature for the transaction to be rebroadcasts to the miners for confirmation. It is advised to use a cryptocurrency wallet that selects the miners fee automatically. This will help you to avoid such scenario where your Bitcoin transaction gets stuck in the blocks for hours. It goes into the Mempool short for memory pool , which is basically a waiting area for unconfirmed transactions. This site shows the current state of the Bitcoin Mempool.
The different colors represent different fee-levels. Blue is for transactions with satoshis per byte, green for , and so on as per the legend on the left.
As you might expect, the higher the fee, the quicker it will be processed. Every transaction has to be checked and confirmed by the computers that maintain a full copy of the Bitcoin blockchain. They do this by verifying your transaction against the history of the blockchain. This is a computationally-intensive process, and one of the major features that gives the Bitcoin network its strength.
Nodes - also called miners - are compensated for this work with the fees that every sender must pay to send a transaction. Once the nodes are satisfied that your transaction is legitimate, it is accepted into a block and broadcast on the network. At this point, your transaction has one confirmation. As other nodes pick up the block and verify it, the number of confirmations will increase.

Each transaction takes the same amount of hash power to confirm, regardless of size. This can create a bottleneck at times of high congestion, where not even small transactions can sneak through. Fluctuating network hash power can influence this, too. When a disequilibrium occurs, prices change to rebalance the network. For example, some recent research uncovered one reason for recurring spikes in network congestion and subsequent spikes in transaction fees.
This was an inadvertent effect of BitMex processing all withdrawals at the same time each day. They have since announced that they will begin batching transactions, which spreads them out across the day and reduces congestion. The lower the fee, the less incentive miners have to verify your transaction.
As you saw above in the snapshot of the Mempool, the bulk of pending transactions are green and blue, i. There is little incentive for miners to process these when they could be expending their hash power on more lucrative transactions. It looks something like this:. This is what an unconfirmed transaction looks like. You can see that it is not included in any block, but is still in the Mempool.
If we compare the fee paid for this transaction If you have crypto on Coinbase that you want to withdraw to another wallet or sent to someone else, you may be wondering how long it takes.
