In Bitcoin system, transactions are prioritized according to transaction fees. Transactions without fees are given low priority and likely to wait for confirmation. Because the demand of micro payment in Bitcoin is expected to increase due to low remittance cost, it is important to quantitatively investigate how transactions with small fees of Bitcoin affect the transaction-confirmation time. In this paper, we analyze the transaction-confirmation time by queueing theory.
We model the transaction-confirmation process of Bitcoin as a priority queueing system with batch service, deriving the mean transaction-confirmation time.
Numerical examples show how the demand of transactions with low fees affects the transaction-confirmation time.
We also consider the effect of the maximum block size on the transaction-confirmation time. Figure 1. Trend of fee-amount distribution over time. Figure 2. Trend of transaction-arrival rates of two priority classes.

Received: May 31, Download: Full-size image PowerPoint slide. Mean [s] Note: This guide has been updated to reflect changes made in Electrum 4. If you have an older version you will need to upgrade. The form on the send tab is used to send money. The amount you enter there is the amount the recipient gets.
To control how much you spend in fees you click pay and then advanced to see this window:. As you can see fees depend on the size of your transaction in bytes and the fee rate in terms of satoshis per byte. There are ,, million satoshis in a bitcoin. The recipient gets 0. So how long will your transaction really take to confirm? Because of the decentralized nature of the bitcoin network there is no way to tell with certainty. We can only estimate. The further to the left you drag the slider the lower the fee but the longer the transaction takes to confirm and the opposite is true for the right side.
There are three options for fee estimation algorithms that you can choose using the selection list next to the slider:. If you pause your mouse cursor over the fee slider you will get a tooltip explaining how long the transaction will take to confirm.
In the case of ETA that will be how many blocks. Note that average is not the same as always. Sometimes we get blocks mere seconds apart and sometimes it can be hours between blocks. Since an average block contains 1. The number of inputs and outputs determines the size of your transaction. If you regularly received small amounts of money from faucets or mining pools in the past your transaction would be very large because of the large number inputs so you would pay a relatively high fee.
How should i do it? Why did you make this change? The ability to adjust at the same time the fees and the amount to be sent � it was great. The transaction is showing as Paid but the bitcoin was never received to the recipient.. Garbage wallet!! I really need help figuring this out. Please, i need help. I use electrum every day and transfer hundreds sometimes thousands of dollars from a multitude of places and people and have never had an issue.
Except when I was a grouchy ignorant grumpus who didnt know how to use it and lost funds. Guess what? So far this wallet is hot garbage. Im on the latest version 4. When I try to transfer and hit pay nothing happens. Electrum just shuts down. I can copy and paste this comment so many times, as it is such a multi use statement.
SMH, educate yourself with the software and the way it works. Better yet get the entire For Dummies series and make sure you emphasize the Crypto currency one. Quit crying and bitching. Abdussamad please what are you talking. The last simple one-input-one-output Bitcoin transaction I sent cost seven cents. It did take about five minutes of fiddling around before I got Electrum to quit creating an extraneous change address to throw a dust-level amount of sats into, though.
Whoever designed that UI should be banned from developing UIs, or maybe sent to a reeducation camp where guards beat him in between struggle sessions and lessons on good design practices. I might actually be forced to learn Python so I can unfvck that dialog box. These users are just not willing to learn how bitcoin and electrum work. They dont understand the complexities and miniscule details that make up a blockchain and the wallets that we have to use to make use of crypto.
I have no issues at all and send thousands of dollars weekly. Does this meen if i try and transfer out of electrum, back to Swytfx, I will lose whats left in more fees??? Cost me a total of. Thanks Electrum, for ripping me off. So this means that Electrum is not a scam� The whole Bitcoin is! And when the bankers will make their own centralized crypto, we will be at the mercy of even bigger criminals and opportunists than just miners� The global parasitic banking system.

So to increase the fee, your wallet intentionally creates a double spend of it that has a higher transaction fee. However it isn't just a pure double spend; there are additional conditions the original transaction and its double spend must meet before nodes will replace the original. When you increase the transaction fee, the wallet checks that the original transaction met certain rules, then it creates the double spend to meet the replacement rules.
The wallet should recognize that the original transaction has been replaced, but if it does not, you should be able to force it to.
Because the replacement confirmed, you should be able to right click on the original transaction entry and choose the "abandon transaction" option to keep it out of balance calculations other things. It will remain in your transaction history, but have no effect on anything. Increasing the transaction fee is literally trying to replace the transaction. Some sites will detect that as an "attempted double spend" - it literally is, but in this case it is desirable.

I don't know much about bytes and output. I have traded other altcoins on Bittrex exchange and converted it into BTC to take profit. I am not sure about input vs output here. Can you please explain something about Input and Output remember, BitGo gives fresh address which is valid only for one transaction. I assume you meant a lot of inputs when you attempt to send from BitGo wallet?
Like this one. If you try to consolidate all the BitGo deposits, you will be charged for each one. A transaction with 1 input and 1 output is approximately Bytes. Each additional inputs will add approximately Bytes, and each additional output will add approximately 34 Bytes to the transaction.
I just transferred 0. I am worried now, not because of the amount, just because I want to transfer big amount asap. Can you please explain what could be the reason? I only sent 0. I am not sure. Nothing to worry about here, is just Bittrex's way of handling withdrawals. They probably consolidate several withdrawals from different customers in the same transaction.
Your withdrawal will not be affected by how they handling withdrawals. Your fee is 0. The exchange where I want to deposit uses BitGo "pay as you go" service and it always worked fine for us. Am I missing something. The info they have is either outdated or still using the amount some people still commit from the congestion for the past days. Perhaps this graph is clearer : btc.
Hi there, I think you misunderstood me. For some reasons there is a big difference between your given link and this one: bitcoinfees. All of them should confirm within blocks, the fee recommendation shown in that page is inaccurate.
Allow me to further ease your mind : blockchain. It got confirmed within 7 minutes or simply 1 block because right now the bitcoin network is no longer congested and fees are relatively cheap once more. Show 1 more comment. Sign up or log in Sign up using Google. Sign up using Facebook.
