Unconfirmed for over 30 minutes on blockchain.info. I have transactions sitting for over 30 minutes now and I paid a transaction fee of .0001 to .0002 for each of them. A question: If I use multibit or bitcoin-qt, will the transactions be faster?

'unconfirmed' transactions for more than 5 month now. What can I do?

I used a not-so-great app (NOW I know) to transfer some btc. The app didn't send any fees, so the transactions were left out. Yes, I am wiser now.
So I have these unconfirmed transactions waiting with the btc left nowhere. One of the transactions happend to be go to /millionmakers. The first transaction was startet 2016/06/20 (ID: d2a3337278e373380954b6853bad93f52e17cd7ace688cf9c4462d20723899bd)
When I track it, blockchain.info always shows a 'recieved date' from today of yesterday, following ever since.
What am I doin wrong and what can I do to get a) my coins back or b) complete the transaction so that /millionmakers gets them?

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

But in practice there's more going on right now than there's ever been in the last few years. You just have to look in the right places. Here's a few days of documented github activity from the bitcoin slack and I've a feeling there are hundreds more people working on Bitcoin projects outside of the work being done by core:

8076 VerifyDB: don't check blocks that have been pruned

If a pruning node ends up in a state where it has very few blocks on disk, then a node could fail to start up in VerifyDB. This pull changes the behavior for pruning nodes, so that we will just not bother trying to check blocks that have been pruned.
I don't expect this edge case to be triggered much in practice currently; this is a preparatory commit for segwit (to deal with the case of pruning nodes that upgrade after segwit activation).

PSA: Clearing up some misconceptions about full nodes

It's time to clear up some misconceptions floating around about full nodes.
Myth: There are only about 5500 full nodes worldwide
This number comes from this site and it measured by trying to probe every nodes on their open ports.
Problem is, not all nodes actually have open ports that can be probed. Either because they are behind firewalls or because their users have configured them to not listen for connections.
Nobody knows how many full nodes there are, since many people don't know how to forward ports behind a firewall, and bandwidth can be costly, its quite likely that the number of nodes with closed ports is at least another several thousand.
Nodes with open ports are able to upload blocks to new full nodes. In all other ways they are the same as nodes with closed ports. But because open-port-nodes can be measured and closed-port-nodes cannot, some members of the bitcoin community have been mistaken into believing that open-port-nodes are that matters.
Myth: This number of nodes matters and/or is too low.
Nodes with open ports are useful to the bitcoin network because they help bootstrap new nodes by uploading historical blocks, they are a measure of bandwidth capacity. Right now there is no shortage of bandwidth capacity, and if there was it could be easily added by renting cloud servers.
The problem is not bandwidth or connections, but trust, security and privacy. Let me explain.
Full nodes are able to check that all of bitcoin's rules are being followed. Rules like following the inflation schedule, no double spending, no spending of coins that don't belong to the holder of the private key and all the other rules required to make bitcoin work (e.g. difficulty)
Full nodes are what make bitcoin trustless. No longer do you have to trust a financial institution like a bank or paypal, you can simply run software on your own computer. To put simply, the only node that matters is the one you use
Myth: There is no incentive to run nodes, the network relies on altruism
It is very much in the individual bitcoin's users rational self interest to run a full node and use it as their wallet.
Using a full node as your wallet is the only way to know for sure that none of bitcoin's rules have been broken. Rules like no coins were spent not belonging to the owner, that no coins were spent twice, that no inflation happens outside of the schedule and that all the rules needed to make the system work are followed (e.g. difficulty.) All other kinds of wallet involve trusting a third party server.
All these checks done by full nodes also increase the security. There are many attacks possible against lightweight wallets that do not affect full node wallets.
This is not just mindless paranoia, there have been real world examples where full node users were unaffected by turmoil in the rest of the bitcoin ecosystem. The 4th July 2015 accidental chain fork effected many kinds of wallets. Here is the wiki page on this event https://en.bitcoin.it/wiki/July_2015_chain_forks#Wallet_Advice
Notice how updated node software was completely unaffected by the fork. All other wallets required either extra confirmations or checking that the third-party institution was running the correct version.
Full nodes wallets are also currently the most private way to use Bitcoin, with nobody else learning which bitcoin addresses belong to you. All other lightweight wallets leak information about which addresses are yours because they must query third-party servers. The Electrum servers will know which addresses belong to you and can link them together. Despite bloom filtering, lightweight wallets based on BitcoinJ do not provide much privacy against nodes who connected directly to the wallet or wiretappers.
For many use cases, such privacy may not be required. But an important reason to run a full node and use it as a wallet is to get the full privacy benefits.
Myth: I can just set up a node on a cloud server instance and leave it
To get the benefits of running a full node, you must use it as your wallet, preferably on hardware you control.
Most people who do this do not use a full node as their wallet. Unfortunately because Bitcoin has a similar name to Bittorrent, some people believe that upload capacity is the most important thing for a healthy network. As I've explained above: bandwidth and connections are not a problem today, trust, security and privacy are.
Myth: Running a full node is not recommended, most people should use a lightweight client
This was common advice in 2012, but since then the full node software has vastly improved in terms of user experience.
If you cannot spare the disk space to store the blockchain, you can enable pruning. In Bitcoin Core 0.12, pruning being enabled will leave the wallet enabled. Altogether this should require less than 900MB of hard disk space.
If you cannot spare the bandwidth to upload blocks to other nodes, there are number of options to reduce or eliminate the bandwidth requirement. These include limiting connections, bandwidth targetting and disabling listening. Bitcoin Core 0.12 has the new option -blocksonly, where the node will not download unconfirmed transaction and only download new blocks. This more than halves the bandwidth usage at the expense of not seeing unconfirmed transactions.
Synchronizing the blockchain for a new node has improved since 2012 too. Features like headers-first and libsecp256k1 have greatly improved the initial synchronization time.
It can be further improved by setting -dbcache=3000 which keeps more of the UTXO set in memory. It reduces the amount of time reading from disk and therefore speeds up synchronization. Tests showed that the entire blockchain can now be synchronized in less than 3 and a half hours (Note that you'll need Bitcoin Core 0.12 or later to get all these efficiency improvements) Another example with 2h 25m
How to run a full node as your wallet.
I think every moderate user of bitcoin would benefit by running a full node and using it as their wallet. There are several ways to do this.
So what are you waiting for? The benefits are many, the downsides are not that bad. The more people do this, the more robust and healthy the bitcoin ecosystem is.

Found a very old bitcoin wallet, uncertain of contents

I recently dusted off an old laptop and noticed a bitcoin wallet on it. It shows three transactions:
  1. 5 bitcoin received
  2. 3 bitcoin sent
  3. 0.01 bitcoin sent
Leaving a balance of 1.99 bitcoin.
However, the Balance shows 0.00 BTC, with Unconfirmed: 1.99. The Wallet also say it's "out of sync".
Can I recover these 1.99 BTC? What's the deal here
Edit: It also shows a message "URGENT: Alert key compromised, upgrade required."
2nd Edit: The wallet is bitcoin-qt, and the first 2 transactions are from 2011, the 3rd from 2014. No clue when it was last upgraded.

Bitfinex btc deposit missing

Hello, for some unknown reason the deposit I made, by sending some btc from my bitcoin-qt wallet, has been confirmed in the blockchain but isn't available in Bitfinex. Bitfinex is showing the status as unconfirmed but also shows two numbers. The first is continuously changing and shows (as I guess) the number of blockchain confirmations (603/3). The second number is always 3 but I don't know what it means. With a btc address Explorer I can also see that the Bitfinex wallet address I used ( output) was already used as an input for another transaction (I didn't initiate). So I guess this was made by Bitfinex. Is there anybody else with the same experience ?

Bitcoin Core: Transaction Details. What does "Status: Open for 202692 more blocks" mean?

First transaction since mining in 2013 and sent all my bitcoin (0.14) to an exchange from the Bitcoin Core wallet but mistakenly set the fee as 1.003 sat / byte and transaction stuck since 28 nov.
Have tried multiple accelerators but no joy. Was hoping it would be dropped by now but no luck, have not been broadcasting with the wallet.
Tried deleting the mempool.dat to abandon but now I have to download 6 years of blockchain to confirm the transaction so the balance shows up in the wallet.
Does the open status relate to dropping (abandoning) the transaction?
https://blockchain.info/tx/e3d6f95abbe2af52d7907a4a034cb8ee8a1231404ce8e07e45c8b09c29e9ca76
Edit: Still no clue about the question in the title.
After some research here is the solution to my problem for any other noobs with a stuck transaction made up of many small inputs.
ELI5 on inputs is think of each input as a denomination of currency like coins and notes For my mining as was paid in the equivalent of loose change with many small inputs.
Each input has a number of bytes so a transaction with many inputs is like paying for something worth $100 with loose change, bulky and slow. I need to create a transaction to another address to convert my change to a note but it will cost a fee to do so.
In Bitcoin-qt i set the walletbroadcast=0 option and deleted mempool.dat.
Downloaded the blockchain again to confirm each input and marked the stuck transaction as abandoned, otherwise I would have ran zapwallettxs option to remove it.
Reason for doing it this way is I still had a couple of unconfirmed inputs from mining i didnt want to lose.
Next i downloaded Electrum and did not import the private key, instead set up the sweep private keys option to consolidate the inputs to a new addreas and set the tx as an rbf with the fee at 50 sats/byte.
Just waiting for confirmation, if no joy in 72hrs will either increase fee or wait for fees to drop.
Can now use original address to claim any btc forks safely.
Hope this helps someone.

I have a Bitcoinfession and a plea: Don't gamble.

Hi everyone, I know very few people will see this and that's okay. I decided after a week of severe depression, anxiety, self-loathing, and general fucked up thoughts that I needed to talk about what I did. On the scope of a confession, it isn't much to some people, but to me it is a huge and daunting fuck up that I'll be paying out the nose for. The reality is I might even be homeless due to this. I used a throwaway for this because a few people I know have my primary acct and I can't bear the shame of them knowing yet.
To get to it, I made a huge mistake and lost all my money. ALL OF IT.
If it isn't obvious already, I don't have a lot of money. I am not a all that familiar with bitcoin and only recently began taking part in the community. /Bitcoin has been my bible and go to source nearly every day for the last 6 months. But again, I don't have much money and I decided that I have a this tremendously good feeling about where bitcoin is going so I warily invested in a couple coins around January 2nd at about 809 a coin from coinbase. I was terrified of losing what I put in. Then the next day, the price jumped about $30! I was ecstatic! I was amazed! I couldn't believe that my investment had begun working for me after only a day! It was a great feeling.
At the same time of all this, I had just finsihed up a huge ordeal with Bank of America over fradulent charges on my debit card that sent my account into the negative and had intitially accured almost $1000 in overdraft and other fees. It took months to get all my money back and in the end still lost out on about $200 dollars. Needless to say, I was more wary of my bank than bitcoin at this point and bitcoin was GIVING me money instead of giving it away. So I did the only logical thing I could think of at the time and put the rest of my savings into BTC.
And guess what? It went up again! I was so happy with my decision that I started reading more and more about BTC.
Then the fluctuations in the BTC market started happening. I started to get nervous because the only cash I had was losing value and fast. I knew that it had a habit of fluctuating like that but I never had any money invested before. The anxiety was real for me every day I'd hop on /Bitcoin and see the news about mtgox ( then after that the silkroad 2 hack.)
So, about a week ago when coinbase's price was plummeting still due to gox's problems and bad press and so on I started getting nervous. More nervous than I had been before. My "investment" had lost almost 200 a coin and I was sick to my stomach watching and waiting for the price to come back up like it "always" does.
I was posting around a few forums and asking questions about what I should do? What could I do in the mean time? Should I pull out and take my losses? I got to talking to this guy on one of the forums who seemed to know what he was talking about. He mentioned the dice site satoshi bones and how he was in the same spot as me, made one bet and came out 10BTC richer. Even sent the tx ids. It was awesome to see and was even more awesome to imagine. He went as far as to send me .05 btc (holy shit!) and said "Make a few bets and watch, some of the odds are great."
So I did that. I sent a few bets of .001btc and made nearly .5 btc in 5 minutes. I was hooked. I was going to make my money back. I was going to make a few bets and get out with what I put in, no more.
So I proceeded to make bigger bets. I was making money. I was getting good at watching and "considering the odds." It wasn't really the case, I was just geting lucky here and there. I had no idea what the fuck I was doing.
Then the transaction malleability thing happened. Or, rather, it was probably happening the whole time. I don't know. I don't know what it did to my MultiBit account, but it was sending my coins and not updating my balance. I was losing more than I knew because the double spends ended up looking like I had more in my overall account than I did. At one point, it appeared that I had TRIPLED my initial BTC investment over all and I was nearly crying with joy.
Then I couldn't access my funds. It said I had a "Balance" of 30btc, but "Spendable" was .05. I knew that it took a little while for the transactions to get through the system and clear but minutes turned into hours and hours into days.
When the whole story about the transaction malleability broke into full swing I started tracing my tx IDs back. I was a nervous wreck at that point. I had so many double spends and unconfirmed transactions that there was no way to actually find out how much I truly had left. When I looked through multibit's logs, it had mulitples of the "wins" that I knew I had but numerous tx Ids. I couldn't keep track of it all. Attempting to "reset" the blockchain on Multibit would only cause it to crash (probably because I had sent and received sooooo many unconfirmed transactions back and forth between that game.)
I decided to grab my private keys and attempt to use Bitcoin-QT to sort it all out to no avail. It too said I had a balance around 30 BTC unconfirmed (a mind blowing amount of money for me!!!!!) I relaxed and decided I would just have to wait it out to get my money and I'd hold off on grocery shopping until the weekend (today.) Even if I had half of that after it all cleared up, I'd have made a HUGE profit.
About two days ago everything calmed down and my balance began fluctuating like mad on both the Multibit client and Bitcoin-qt. It went UP at one point to 40 BTC even! Then transactions started to disappear. Mostly, the transactions that disappeared were the "wins." I assume this is because all of the unconfirmed txs or double spends started being pushed out of the system? I have no idea.
I'll take a second to mention that I've never had an interest in gambling whatsoever. I've been to vegas, played a few slots, sat in for some poker and blackjack, would lose and just walk away. However, the last couple days I was consumed by the dice game. I thought I was making incredible money, hand over fist.
Yesterday, my balance completely cleared up. I'm broke. I have nothing left. I pissed away even my winnings (maybe 3btc) I had before the transaction malleability started fucking things up. I cried for the first time in 10 years yesterday. Today, I cried again.
Over the last week I fell into a depression and was overcome by this urge to just stop existing. Not really suicide at first, but, more of a "I want to close my eyes and let it all blow over." Then, when that didn't happen, I did start considering suicide. I have no money left. I don't know what the fuck I'm going to do for rent, for food, for gas, for my fucking books next quarter. I moved to california on my own about 3 years ago and have zero family in the area. I don't have family to lean on finacially whatsoever (I come from a seriously bad luck/misfortune/poor family.) Monday I'll be heading to my university to find out what I can do and if I qualify for any loans. Or something. I don't know. But right now, I need to tell people and persevere and try to make it out of this.
But, my point of posting here isn't a pity party or to draw out "sorry for the bad luck" responses. I did this to myself and this pales in comparison to the bad luck others have had.
I want people to use my sincere and obvious FUCK UP as a lesson. I got caught up thinking I was making money. I wasn't fully aware of what was happening during the transaction malleability shit and made decisions without fully comprehending the situation (and it is NOT the fault of Mulitbit or the dice game even if I wanted something to blame.) Most of all, I was GAMBLING my money away. It was greed and poor decisions. But mostly greed.
So, I fucked up. I don't want YOU to fuck up like I did. Please look at the story and realize that it can happen to anyone without fully thinking through your decisions and having a grasp on the situation. And SERIOUSLY consider when you're putting too much money at stake when gambling. You could regret it and be in a shitty spot like myself. Thanks for reading.
TL;DR Holy shit I wrote a novel. Sorry. In short, I inadvertently gambled away my only $7000 during the transaction malleability crisis and it is no one's fault but myself. I am now broke and terrified and I don't want YOU to suffer like I did. Do not gamble and do research before you do anything with your money especially if it is all you have.
EDIT: Though my intial reason for posting was NOT to focus on why my balance said one thing and the actual balance was another, here is what the balance looks like on my Multibit client right now. However if you look at the blockchain, that's clearly not the case and hasn't been for days and days. These are the addresses I used off and on. Not all of them but those were the most active I think. 17cHzgxRLumqfu6UAddUrJmTujd7goHLrx 1BAKHq37qj1xekitr7adXapLqFrVtAhm8A 1KLug6D1mXoyS12BZipyQ8WHAdNzDmQxMp. Also, when I opened the Client today it seemed to send or revieve "stuck" transactions? I don't know what to tell you all beyond that.

Bitcoin transaction takes 2 days already..

I heard stories of other people having the issue that their bitcoin transactions takes way to long... I personally never had issues like this untill now.. https://blockchain.info/address/3PdqKa1KVM4iTxQtSbKkwsqJBEHAVP5bUf
It's unconfirmed for 2 days already while the fee is normal.. Anyone else having this issue lately?
If i check the estimation time on https://www.blockonomics.co/api/tx?txid=78eb50b54c175c11a2b116327ff1dc13ab3c757fb76fcb3556b97fb0b6c0a706&addr=3PdqKa1KVM4iTxQtSbKkwsqJBEHAVP5bUf
It should have been done already a long time ago.. but i am still waiting and waiting.. What can i do to "speed" this up?

Average Fee Bitcoin Transaction Stuck for 24+ Hours - Offering BTC tip for help!

Hi all - quick question for some of the more knowledgeable users of the sub. With the recent spike in price I'm looking to sell some of the bitcoin I have - which I've been doing over the course of the week without issue.
Yesterday when the price hit 19k, I tried to send the remaining contents of my Bitcoin QT wallet to my coinbase wallet for sale. I did three separate transactions (mostly because I'm unnecessarily paranoid about sending Bitcoin to the wrong address), and only one of the three has been confirmed on the network.
I paid the highest fee the "price slider" on my wallet would allow on the three transactions, which was supposed to confirm them within 2 blocks. I checked https://bitcoinfees.earn.com/ and made sure to pay the recommended .0039mBTC/byte (increased to .004mBTC today) I paid .0039mBTC/byte and yet only 1 of the 3 transactions has been confirmed. My suspicion yesterday was that the surge in price had congested the network with a plethora of transactions and now I'm stuck with low fee transactions pending forever. I'd like to take advantage of the high price to sell right now, so I'm panicked and frustrated that these bitcoin seem to be stuck floating around in cyberspace.
I'm confused because 1) I'm a noob and 2) I haven't seen anyone else really complaining about this issue. I read a bunch of news articles talking about the recent backup in the mempool, but I can't understand why I'm having this issue considering the fee I paid. I'm even more confused that one of the three transactions did go through. Can anyone help me make sense of this? I'd very eagerly send a BTC tip to anyone who can help me out! Thank you in advance :)
Here is a link to the transaction details: https://imgur.com/a/O7yMW
Transaction 1: 7c80c4d4366061a1a2caa04bc6ba25780630e698a2b350e31e6ca89f599fc811 Fee - .88933mBTC/225 bytes = .00395mBTC/byte UNCONFIRMED

Unverified transactions and incorrect balance on ancient wallet

Back in '11 my roommate and I were messing around with bitcoin and he sent me .11BTC in 2 transactions. I was using the OSX 0.3.23-beta client. That's as far as I got into it. I came across the wallet the other day and then attempted to send some coin to my wife who has a coinbase wallet. That was weeks ago and it's still unconfirmed. In the meantime I updated to bitcoin-QT and got the whole blockchain and filled my hard drive twice doing it hoping maybe a more modern client would help things out.
Apparently not.
In addition my balance in bitcoin-QT is not what it should be. I had .11 and sent .01 with a .0005 transaction fee but my balance is saying .01BTC. I think my fee might have been too low and that's why it's still unconfirmed, which is fine, I'll survive that but now that bitcoin is worth more than it was and is a useful amount I might want to do something with it. Spend it on something, or keep it around but I'm not sure why the balance is off?
Here's an album with screenshots

[HIRING] Help me get my bitcoin from my 2013 wallet and I'll send you 0.1 bitcoin

Hey guys, so I was into bitcoin about 3-4 years ago but then I put my wallet on a flashdrive and stored it away. Totally forgot about it until now. I downloaded Bitcoin-qt (which is called Bitcoin core now?) and replaced the wallet.dat with my old wallet.dat file.
Now it's up to date, but on the Overview tab I have 0 BTC available and 0 BTC pending, but under Recent Transactions, it shows that I received some bitcoins in 2013. I also see it under the Transactions tab with a question mark in the left cell and "Received with" under "Type" However, its status is: "Status: 0/unconfirmed, not in memory pool". What does this mean? Am I able to get my old bitcoins? If you can help me get the bitcoins from this transaction then I'll send you 0.1 BTC. Thanks!
Edit: I'm on a Mac btw! If you'd like to help, could you post here instead of sending me a PM?
Edit 2: Here's what I get when I type listtransactions in the console of the debug window:
[ { "account": "", "address": "1EQF3dDFp1txt8EYKfVu1vJH3d9BWTAGi1", "category": "receive", "amount": 14.42514751, "vout": 2, "confirmations": 0, "trusted": false, "txid": "bf180dce241d32609220db4808ab8c7920f6ff3b2deca60c2a23dcda9f4eaf95", "walletconflicts": [ ], "time": 1386416832, "timereceived": 1386416832, "bip125-replaceable": "unknown" } ] 
Edit 3: Increasing reward to 0.2 BTC
Edit 4: Here's what I get when I right click on the transaction and select "Show transaction details"
Status: 0/unconfirmed, not in memory pool Date: 12/7/13 03:47 Credit: 14.42514751 BTC Net amount: +14.42514751 BTC Transaction ID: bf180dce241d32609220db4808ab8c7920f6ff3b2deca60c2a23dcda9f4eaf95 Output index: 0

Please help Bitcoin Tx sent with 0 confirmation fee!

Hi Guys,
I am a fairly regular user of Bitcoin. Recently, i switched wallets from QT to Blockchain web wallet as i was having a few issues with the QT. I also updated the settings on my blockchain wallet to 0 fees for transactions as i was planning on hoarding the bitcoin i had.
Today, i had an emergency and transferred BTC to another wallet for withdrawal to fiat and in my anxiety, i forgot to change the fee setting. Now the tx has been broadcasted at 0 fee and i am stuck. I understand that i can double spend the amount but i am not confident of the procedure, is there any way i can cancel this tx from blockchain.info by sending them a message? Also, iirc, there was a method i could check approximately how long the tx would take to process on the blockchain.info website, but cannot remember how i could do so. The current state of the tx is Unconfirmed and it does say Estimated Confirmation Time: Very Soon (High Priority). Can i be re-assured by this?

I selected "no fee if possible", it's been 5 hours. Am I boned?

I recently sent out a transaction of about 0.06 BTC, and exploring the Bitcoin-qt GUI, I found the option to attempt to have no fee if possible. I know fees are inventive for my transaction to be confirmed, but I was just curious, and ticked it, while keeping my standard fee the same as it always was.
Now, it's hours later, and they're still unconfirmed. I know it's too late to magically untick that box, but since I can't...what happens now? I don't just want that small chunk of change totally vanishing, being in limbo forever. It's there anything at all I can do now to get it confirmed, or possibly rejected back to me?

Transaction stuck... because I'm stupid. Too low of fee and need to fix. Help please!

Using bitcoin-qt I sent two transaction to another wallet of mine but somehow managed to set too low of a fee I believe. Both transactions are currently just sitting there unconfirmed and also neither are showing up on blockchain.
Is there any way I can either cancel the transaction or change the fee so that these will eventually get processed?
I've tried rescanning and rebroadcasting from a different computer as directed from a different site, but that didn't help.
Still nothing showing on blockchain and 0/6 confirmations.
I'd really like my money to transfer!
