Can I use unconfirmed Bitcoin transaction?
An unconfirmed Bitcoin transaction can be fixed in two ways: by using “replace-by-fee or RBF protocol” or “higher fee double-spend transaction.” A Bitcoin transaction cannot be reversed once it has been confirmed.
Reverse the Unconfirmed Transaction
You can reverse your Bitcoin transaction if unconfirmed within 24 hours. However, ensure that the transaction is genuinely unconfirmed. That means you have to wait for 24 hours.
All bitcoin transactions require a miner fee to be confirmed by the bitcoin network. When sending bitcoin you will be prompted to add a miner fee to make sure the transaction gets confirmed. If an insufficient fee is included, your transaction may never confirm.
How can I speed up confirmation times? There is no way for you to speed up the rate at which blocks are added to the blockchain. However, you can speed up the likelihood your transaction is included in the next block by increasing the fees you pay for the transaction, which makes it of higher interest to miners.
No, we're unable to cancel or reverse your transaction. Even many advanced cryptocurrency users can recall an incident when they failed to double-check their transaction details and they accidentally sent funds to the wrong recipient, or sent the wrong amount.
If the transaction receives a confirmation, your wallet should update automatically. If the transaction does not confirm, the funds will be spendable again from the sender's wallet. This may take up to 30 days.
Bitcoin payments are irreversible
A Bitcoin transaction cannot be reversed, it can only be refunded by the person receiving the funds. This means you should take care to do business with people and organizations you know and trust, or who have an established reputation.
Due to the irreversible nature of cryptocurrency protocols, transactions can't be cancelled or reversed once initiated. If you sent funds to the wrong address, you'll need to contact the receiving party and ask for their cooperation in returning the funds.

What is Bitcoin Mempool? The transactions which are sent on the Bitcoin Network are not added directly to the blockchain. All of the valid transactions have to enter a waiting area before they are accepted in a block. This waiting area is known as the mempool.

When a blockchain network experiences peak traffic, it causes delays, a backlog of transactions and also pushes up transaction fees as demand outweighs supply and miners can pick and choose what they process. Even if you put in a healthy transaction fee, you might be in for a wait.
A Bitcoin transaction is confirmed when it is combined in a block with other transactions and added to the blockchain. A new block is added approximately every 10 minutes, and every new block added thereafter means greater assurance of an irreversible transaction.
Yes. Bitcoin is traceable. While bitcoin can be minted, moved around, and stored without the oversight of any central authority like the government, each bitcoin transaction is recorded on a permanent publicly available ledger known as the blockchain.
You are able to cancel a BTC withdrawal request to an external address under Account Funding/Withdraw BTC ONLY IF the withdrawal is still IN-PROGRESS and the transaction has not been broadcasted to the blockchain. In this case, there will be a 'Cancel' button next to the request.
In order to cancel a transaction, you need to do the following. Click on the pending transaction and find a field called nonce on the screen. Record the value in that field (a number). Start a new transaction.
How do I? Hi Kehinde, To cancel a transaction in your app, or on the website, go to the menu, then click on Transactions. Transactions that can still be cancelled will be listed as "pending" in your transactions list. Click on the transaction in order to open it and then select Cancel.
If you have sent a transaction that is taking a long time to confirm, you can speed it up by using our increase fee feature. This resends your unconfirmed transaction with a higher fee. Bitcoin miners prioritize transactions with higher fees when selecting transactions to include in a block.
A pending transaction will affect the amount of credit or funds you have available. Canceling a pending transaction usually requires contacting the merchant who made the charge. Once a pending transaction has posted, contact your bank or card issuer to dispute it.

What Should I Do If My Transaction is Stuck in the Mempool? As a rule of thumb, if you wait long enough (usually around 48 hours) your transaction will drop from all of the Bitcoin mempools and the funds will be returned to your wallet.
An empty mempool means fees can be kept to an absolute minimum. That is good news for the network as a whole. Bitcoin miners may not like this development too much, though. Their earnings will decrease slightly when network fees drop off.
A mempool (a contraction of memory and pool) is a cryptocurrency node's mechanism for storing information on unconfirmed transactions. It acts as a sort of waiting room for transactions that have not yet been included in a block.
