How can wallet send unconfirmed bitcoins?


I created a wallet in android app. I bought 0.2830 BTC onto my new address. Then I made another address, tried to send 0.0001 BTC to that address (without a fee / 0 fee). Now it stays unconfirmed as you guessed. I just wanted to kind of test sending btc between addresses.
The problem is I want to send larger payments with a fee to another address but android client says "No free outputs to send". Why is it that if I have one unconfirmed transaction all of my btc address balance becomes unusable?

Because you only have the single input to spend. Think off it like you received a 0.2830 BTC bill and now you try to spend 0.0001. You have to use the entire 0.2830 BTC bill for that. Once the transaction is confirmed you will be able to use the change.

I have now spent multiple hours reading and searching the internet for some quick solutions to this problem. But as I am relatively new to bitcoins (although I have IT and Computer...

This question already has an answer here:

After 35 hours and still Unconfirmed bitcoin deposit to my wallet after I sweeped the bitcoins I have in my paperwallet which I created on

Hello everyone, this is my first time having a problem with unconfirmed bitcoin transactions! I hope somebody can help me resolve this issue by sharing their knowledge and experience and point me in the right direction, thank you so much in advance!

About 35 hours ago, I used the wallet to sweep a bitcoin paper wallet private address where some of my bitcoins were stored!
(I created the paper wallet address on, and I have been storing bitcoins like this and sweeping it with wallet for the past year and a half without ever any problems regarding delayed transactions.)

Anyway, this time after the wallet was successfully sweeped, and the bitcoins were transferred from my paper wallet to my...

The latest versions of our wallet now use a dynamic fee structure (which you can read about here) to determine appropriate fees for your transactions, so some of the information in this post no longer applies.

If you have a pending transaction that is taking an abnormally long time to confirm, it may be due to network congestion. To find out more about how network congestion can affect your transaction, check out this article in our Support Center.

This is a Blockchain Quick Bit, where we cover the basics of a topic, or product, to help you understand it better. This Quick Bit is intended to help you learn about bitcoin transaction fees. Bitcoin transaction fees are one of the many benefits for consumers and merchants to utilize bitcoin, and is an attractive aspect of the digital currency. Currently bitcoin transaction fees can average to around .04 cents USD (or 0.0001 BTC) per transaction.

Bitcoin transactions are in place as an incentive to miners when...

If you’re reading this post I assume that like many others, you sent a bitcoin transaction and was kind of confused as to why it’s still listed as “unconfirmed” or “pending” after a few hours or so.

I mean Bitcoin transactions are supposed to be instant right?

In this post I want to try and explain in a very basic way how a Bitcoin transaction works and why the fee that you attach to each transaction has a crucial role in how long it will take the transaction to go through the network.

Here’s what happens when you send Bitcoins to someone

Whenever you send someone Bitcoins, the transaction goes through different computers running the Bitcoin protocol around the world that make sure the transaction is valid. Once the transaction is verified it then “waits” inside the Mempool (i.e. in some sort of a “limbo” state).

It’s basically waiting to be picked up by a Bitcoin miner and entered into a block of transaction on the Blockchain. Until it is picked...

Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank.

A cool function of Bitcoin not mentioned in introductions is its message signing and verification feature. I'll use the Satoshi client on a Mac as the example but the same functions are available in the wallet at and in any decent Bitcoin client.

Suppose you have a dispute with a vendor you paid in bitcoin. They say you didn't pay them the correct amount or they didn't get paid at all. So you show them the record of the transaction.

Great, says the vendor, but how do I know that's your coin?

In the Satoshi client, go to the "Receive Coins" tab. At the bottom, you'll see an option that says, "Sign Message" (you can also go to File > Sign Message). Enter the Bitcoin address that you own that initiated the transaction (that's the address to the left of the green arrow in the transaction record mentioned earlier) into the address form. Write your message and then hit the "Sign Message" button.

The signature generated is unique to the address...

How to export your private keys from and move the balance to any address using electrum

The Problem is a popular online bitcoin wallet provider. It’s name often confuses new bitcoiners into believing that is the blockchain ledger. As an online wallet service provider the company must keep a database of their customer’s wallet identifiers and hashed passwords along with wallet balances.

Due to the recent DDOS attempts on the bitcoin network it seems that the wallet balances in the database might have fallen out of sync with the actual wallet balances on the bitcoin network. As a result users are getting the following errors when trying to send bitcoins from their wallets:

The website can be used as a mobile wallet thanks to its Android app. is best known as Bitcoin's block chain explorer, but it also has a wallet feature where you can send and receive bitcoins. With the Android app, you can access all this while you're on the move.

The app opens up asking you either to create a new account or to pair with your existing wallet. Registering on the website is better as there are a few pieces of data to keep a record of. Pairing with the website involves opening your account details on the website, and clicking on the devices section, and there you'll find an option to display a QR code. This can then be scanned by the app on your phone, then the pairing is complete. As far as the app design goes, it is easy to pair, it just takes a little digging to find the QR code on the website.

Once paired, you are shown a summary of your wallet, including balance and a list of transactions....

People often claim that with Bitcoin “you can send money between any two points on earth for free”. While that is true in some cases, sometimes a transaction fee is required. The fee, when it is required, is usually worth less than 40 US cents.

The fees go to the miners to incentivise them to keep mining, which in turn keeps the Bitcoin network secure. They already get a reward of 25 XBT for each block they mine, but this reward halves every 4 years. The plan is that as the block reward diminishes over the time, it will be replaced by transaction fees.

So what decides when you have to pay, and how much?

Well, like everything else in Bitcoin, the fee structure is built into the network rules, which are defined as “what the reference client does”. When you attempt to send coins using bitcoin-qt (the current reference client), it goes through the following steps:

1. Pick which coins to spend

The client has to decide which of your coins to...
