Sometimes its really frustating when transaction does not get any confirmation on blockchain for long long time...nowdays it is happening more regularily...for hours transaction remains unconfirmed on blockchain...what is the reason behind this?

because some blocks are full and the transaction will be put in queue, or you simply didn't pay the reccomended fee, which isn't always 10k satoshi

Yeah, I sometimes don't do the recommended fee and then my transaction takes hours. Now I just use 50k satoshis and the transaction gets confirmations pretty quickly.

It depends on the kind of transaction that you send out. If it's for example a single input transaction, then 0.0002BTC will get it included in the next block. But if you have plenty of inputs bundled into one transaction and you just pay 0.0001BTC or even lower, then yes, it might take a few hours before your transaction gets its first confirmation. For bundled transactions I mostly use 0.0005-0.001BTC depending on the importance of the first confirmation. If there is no hurry at all, I just stick to 0.0002BTC.

You can share with us , your trx id so we can review your problem and yes .. most of this case, you may not set appropiate fee to your transaction
So you need to set enough fee amount if you want to get your transaction confirm quickly !

before sending any transaction, check the number of unconfirmed transactions, if it less that 3000, your tx will get confirmed with the next block with normal fees like .0001 btc. if there are a lot of unconfirmed txs, then you need to pay more fees if you do not like waiting

Thanks for the useful information!

I've generally found a .0002 fee will nearly always get you in the next block. You'll often be overpaying but it's hardly a significant amount

Thank you for sharing these useful informations, I don't know that this is the reason why blockchain sometimes have delays in confirming transactions.
Now I know, so that's the use of recommended fee, I'm glad that I'm always pressing 'ok' on it.

Before it doesnt happen regularily...but now my every second transaction stays unconfirmed despite paying the recommended fees..

Sometimes there are some blocks that are half full (200kb or so) and the transaction gets confirmed easily, sometime it is near 1000kB and the transaction cant be put there and will be queued for the next block. Also the transaction fee has its affect.

I have tried fees lower than 0.0004 and they just don't seem to work for me. Now I just use 0.0005 so that I am sure that I would get into the next block.

It depends on how many bytes does that transaction has, sometimes it can be confirmed with 0.0001 fee and can be included in the first next block sometimes even 0.0005 can't help to much if the size of the transaction is greater.

If there are many transactions in the network therefore it will make the network busy and due to that our transaction confirmations will take long.

I'm not having problem with blockchain every time I'm using it I got confirmations as fast as 2 minutes.
But if not, the longest time would be 7-11 minutes.

There were some fake stress testing being done a while ago, but in my opinion that were only people trying to force the issue of the block size increase. Yes, it did spark some discussion, but it did not bring the house down. People just increased their fees and it resolved most of the issues. Segwit and a hard fork will solve this in the future. ^heh^

Because sometimes is more transaction to confirm.
In a days can be 2000 of transactions in another day can be 20000 transactions.
You need to pay a high fee for a fast confirmation.

I also have noticed that while transacting my money, especially when I try to send a bigger amount of bitcoin, the only reason of it is the fee, if you pay the recommended fee for a transaction then it will not take more time than usual time .

Well I think it takes a lot of time because many miners rest for now because halving is near. It don't usually take a lot of time to get confirmations on blockchain on normal days but now it takes a lot of time. Im lucky if my transaction got 1 confirmation on 1hour sometimes more.

Yeah, there are lots of people experiencing this sort of problem. I believe IIRC that someone might be launching an attack over the network so that the mempool is flooded, or it's simply the lack of sufficient fees.

It's really frustrating though. Not getting the confs you need on your coin.

Just take it easy.There are many reasons why.Forst is blocks are full of transctions so some transactions are put on qeue.And sometimes because of transaction traffic that blockchain cant handle,think how many users online and how many transctions is processed at the same time

because now a large number of people are using bitcoin and they are transacting their money so it will take some time for confirming that number of transactions.

This problem is becoming overwhelming for me. Sometimes there would be hours without a block, and sometimes there would be lots of blocks but my transaction would not be confirming.

The blocks are full sometimes, and that's why it's currently like this. It could also because you set a low fee.

I agree on the last replies ,well it depends on the transactions going to be confirmed before to be succesfull .just like in some banks need to take some minutes to be done. I think that's the only problem on blockchain.
