If you pay a fee to miners on top of the fees that you included in your original tx, then things will quickly escalate into a situation where
"spam" attacks will become more popular. They would run this, just to "double dip" on the fees.
... We should find a way, to
eliminate and avoid this scenario, rather than promoting methods to "repair" it. That said, your thread is still extremely helpful in the
situation we have now... so thumbs up for that.

After about 48 72 hours transactions may be forgotten which means nodes will stop broadcasting it and it is possible that your transaction disappears.
so do we have to find/hire a miner to mine that transaction for us so we can retrieve the bitcoin that the nodes have been forgotten or it will dissappear? I just have this thoughts so in the future I know the answer and not be ignorant about it thanks in behalf of who will answer first. When you broadcast a transaction it propagates through the network in matter of seconds and it stays in the mempool (all the nodes are broadcasting it), now this transaction can not stay there forever otherwise size of the mempool would go up extremely fast to an unmanageable size.
To fix this, nodes will drop transactions that have not been confirmed for a certain amount of time (default in bitcoin core is 72 hours). Not all nodes have this default setting though.
If you are the sender, you can send the same transaction from your wallet (if you are a full node by just opening your wallet and connecting) or you can spend it again.
If you are the receiver, the only thing you can do is to save the transaction hex and push it yourself if it was dropped. do this by adding a ?format=hex tag at the end of blockchain.info/tx/..... links.

Do you have a reference link to that 48 hours and nodes stop broadcasting statement?I would like to read it.
I was mistaken it is 72 hours by default and can be changed.

Thanks for providing this to the community, very helpful.
I once had a transaction for 1.5 bitcoin take over 6 hours for one confirmation. I sent the average fee so I didn't understand WTF was going on. It confirmed eventually/luckily but this is a great topic for people who are in a similar position to what I was.

Feel free to leave bitcoin and bitcoin board and continue to use your favorite altcoins, nobody is forcing you to be here and to use bitcoin.♯what cause delay even after paying the recommended transaction fee suggested by the wallet provider, this has happened ones or twice before ♯
You should have checked your fee/byte versus fee/byte that http://bitcoinfees.21.co/ suggested at the time of your transaction to figure out if it was really a good recommendation or was it far off the mark.I can't tell now with these two information.
and also I was told that exchanges have gentleman agreement with miners to prioritize their transactions over others.
I have never heard such a thing.https://blockchain.info/tx/216adde7507773b3916cb13172835b24ba832861ec63992bf6d982edc86a67dc

I am also very curious what the best fee will be. I have added some fee, but probably not high enough.
Thanks,
Please read the topic carefully before posting. General > #1 and Sender > #1 explains it.https://blockchain.info/tx/940d6d64a76d40b73b38c1d9379ed30a1b0a8fdac1d0f87c2df180eb24ff5b88

Your transactions are 226 bytes and 666 bytes which requires 31,640 and 93,240 Satoshi. Your transactions have half the suggested fee which means there are lots of other transactions with higher fee and higher priority than yours which miners are going to prefer.
Use General > #3 solution for now to increase the possibility of being included in a block.
There is nothing to get worried even if the transaction doesn't gets confirmed after 24 hours. Just view the unconfirmed transaction. If you can see your transaction under that nothing to fear else contact the support team.
After about February 03, 2017, 05:45:07 AM
Can somebody advice me which wallet I should take and which fee to set in future? Currently I use the blockchain.info wallet. I have enough of waiting for 16 hours or more for transactions. I have no problems with paying more fees.
February 03, 2017, 05:06:42 AM

Hello,
I read some things about unconfimed transactions. Usually it takes 1-2 hours. Last week I had to wait for 6 hours. But this time I am waiting for almost 15 hours and still not confirmed. Horrible.
Can anybody give me an indication how long it will take before it will confirmed? Here are the transation details:
https://blockchain.info/tx/216adde7507773b3916cb13172835b24ba832861ec63992bf6d982edc86a67dc
and

thank you for this info.
I was wondering why the transaction was not shown in my wallet instantly.
now I know it was the low transaction fee which caused the delay.

I do appreciate OP for this but what cause delay even after paying the recommended transaction fee suggested by the wallet provider, this has happened ones or twice before and also I was told that exchanges have gentleman agreement with miners to prioritize their transactions over others.

Best Solution , I have been using
Check the unconfirmed amount of transactions before sending .
https://blockchain.info/unconfirmed-transactions
If the amount of unconfirmed BTC transactions is over 10 thousand,
then I send another coin like LTC or ETH instead of BTC.
If the amount of unconfirmed BTC transactions is under 10 thousand,
then I can send BTC knowing it will arrive in ~ 2 hours or so.

What can I do if I'm using a web wallet like blockchain.info? I made a small transaction 2 hours ago. There's not a single confirmation. Is someone spamming the network again?
Read Things to do as sender > #1 (use a tool like http://bitcoinfees.21.co/ to determine the best fees next time) your transaction must have had less than 140 satoshis/byte feeRead General > #3
Also think about changing your wallet.
Thank you. But where in blockchain.info can I know the sizes of each of my transactions?

Blockchain.info offers limited functionality, it is however sets the fee according to your size automatically for you. This doesn't mean it is doing a good job though. That is why I said think about changing your wallet.You can however calculate an estimated size if you insist on using BC.I. A rough estimate is this:
Code:
inputCount*180 + outputCount*34 + 10 ± inputCount*1
refit's "replaceable" the same as abandon transaction in bitcoin core, because there is not such option in core, but maybe they do the same thing?
The funny thing is RBF existed from very early version and it was added in 0.12.0 and I can not find it in bitcoin core (0.13.0 I should upgrade soon :/) apart from mempool which is about relaying the RBF transactions not making them.

You may want to mention in bold that wallets most of the time has nothing to do with your transactions being unconfirmed for a long time because people usually assume that and make threads on specific wallets boards.
