How can we help you today?
Every bitcoin transaction that's sent flows into what's called the mempool short for memory pool before it can be confirmed by miners. When there's a dramatic spike in transaction activity, the mempool can become congested because so many transactions are waiting to be included in the next block.
Bitcoin users across the network may notice their transactions sit as unconfirmed or pending for a longer period of time, and we understand this can cause users to be concerned about the status of their funds.

Why is my crypto transaction 'unconfirmed'?
An unconfirmed transaction means that the transaction has not been included in a witj and thus has not been completed. Most recipients require at least one confirmation to complete the transaction, including Wirex. If your transaction is unconfirmed, usually you just need to wait. Most transactions get completed within a day or two or more if the blockchain is overloaded. In rare cases, transactions with a low or absent fee may get stuck in unconfirmed status for over a week.

With the recent spike in the price of Bitcoin the number of unconfirmed transactions has increased significantly yet again and the Bitcoin blocks are getting closer and closer to being full. This essentially slows down transactions on the network and in order to ensure that your transaction is being processed faster you need to increase the fee over the standard recommended one. While this may be just fine for larger BTC transfers with fewer inputs, if you want to make a small transaction of few Bitcoin cents or a large one with a lot of inputs the network fees can get quite high. If the fee is not large enough and the waiting list is big you can easily end up with your transaction not getting confirmed and included in a block for over a day and that usually causes a problem, especially if you are paying for something in BTC. The solution would be to just cancel any unconfirmed transaction that did not go through for over 24 hours and it is not that hard to do it actually, although the process itself may require some time.

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 ofBitcoin transactions remained unconfirmed for over a day.
Notably, the Ethereum network had similar problems after CryptoKitties caused havoc with its Mempool. Although, as it later turned out, this was an extremely frontloaded success, and the killer dApp is yet to appear on the horizon. A more recent example of a rapid increase in the level of network congestion was related to the Bithumb hack in June. Most probably, the delays and the increased fees were connected to the South Korea-based exchange cleaning out its wallets. Bitcoin is a cryptocurrency that is based on the Proof-of-Work PoW algorithm.
All Bitcoin transactions are conducted with the help of cryptocurrency mining. However, for a given payment to be processed successfully, it has to be confirmed by a miner who gets a block reward for each confirmation. Until confirmed, it remains in the mempool. Ethereum, on the other hand, had this issue resolved by adjusting the blocksize transactlons the network volume.
That is why the Ethereum network was able to handle a three-times-bigger transaction volume back in February. As of now, the blocksize is limited to 1 MB this limit was introduced by none other than Satoshi Nakamoto. These record block sizes were made possible by transactions with numerous segwit inputs created on BitGo with super low fees. Block rewards are the bread and butter of cryptocurrency miners.
Long story short, this is the place where all unconfirmed transactions remain in limbo. The pool unites all the computers that are connected to the Bitcoin Network with the help of Bitcoin mining software. All payments that are yet to be confirmed are transachions in the RAM of a given device. If the mempool size is inching closer to occupying the whole RAM trahsactions, the node is able to automatically discard all pending requests with lower fees.
It is worth pointing out that the mempool is not a queue — different nodes have their own set of transactions that to be confirmed, and they are clearly incentivized to pick transactions that have the highest mining fees.
The more popular BTC gets, the bigger is the size of the mempool. Would better hardware make a difference? The modus operandi of the Bitcoin network presupposes that each block is mined every ten minutes or nearly soand the same timeframe would remain in place even if every miner had a chance to be equipped with super powerful hardware. In order to get all the insights into the current state of the mempool, one simply has to visit the website of a German software engineer Jochen Hoenicke: it displays all current Bitcoin fees along with the current mempool size.

At Coinbaseall stuck payments are carried out what to do with unconfirmed bitcoin transactions the help of the CPFP protocol, effectively tackling one of the most debatable issues what to do with unconfirmed bitcoin transactions the Bitcoin network.

The bottom line is that RBF is a viable option for those who want to confirm their transactions faster by increasing the amount of the fee. Meanwhile, CPFP is more suitable for a sender who fails to persuade the miner to pay a transaction fee instead of.

As mentioned above, the main purpose behind confirmation is to avoid the much-feared double-spending. Meanwhile, the Bitcoin Cash community is already mulling over accepting zero-confirmation BCH transactions in order to give a competitive advantage to the network. Speaking of further innovations, a recent Forbes article suggests that Bitcoin needs a better consensus algorithm that is superior to the current Proof-of-Work PoW.
The system requires a minuscule amount of Proof-of-Work. The scalability issue continues haunting Bitcoin.
