Because of block i think it takes some time before it confirmed and too much complaining so far as you can see there are so much transaction are unconfirmed so far because of too many request and the transactions increases that big.

interesting! there is currently 28K+ unconfirmed transactions according to blockchain.info.
but in my experience this usually happens for two reasons:
1) there is gap between blocks that were found (this is not the case here there were 5 blocks in last hour)
2) there is a spam attack going on (don't know how to find out if this is true or not!)

It's probably some of the same issues we've seen recently, is there a delayed block or a back-up with the chain? There might be some higher-fee transactions happening right now too, and those might be pushing the rest of the transactions back.

[~Bitcoin~]

Inside this all unconfirmed transactions there are several types of transactions like;
-- some random zero fee transactions from newbies thinking fee is optional
-- very low fee for big size transaction which get stucked unconfirmed for several days
-- dust transactions associated with different failed attack attempts on bitcoin network

And recently there been lots of delay between finding blocks which also makes lots of transaction even with recommended high transaction fee getting stucked for several minutes/almost hour.

There might have been 5 blocks in the hour before you posted but steven0021 says that yesterday there were only 12 blocks over a span of 3 hours. Normally there should be 18 blocks over a span of 3 hours so the mempool got filled with unconfirmed transactions. I haven't heard about a spam attack recently.

Can someone please tell me why the last two transactions to this address are still not confirmed.

I think that I have paid more than enough fee.

Thanks

50 satoshi per byte fee is not "more" than enough anymore, but high enough to get your transaction in the next 20 blocks or so. Problem is there's only 12 blocks since 3 hours ago and the latest was 1 hour and 12 minutes ago (which means that you're unlucky.). So your transaction should be confirmed within 6 blocks (or 1 hour average).

Edit:
Whoops. Terrible math in action there. I meant 8 blocks, not 6.

Because of network limitation the maximum transaction capacity has been reached some time ago, the network has been congested and huge delays in confirmations occur since then.

Every time a lot of people have to transact using bitcoin this kind of stuff happens.

The following chart illustrates whats happening:

1 mb block are getting saturated every time these days and also there is so much time gap between finding two consecutive blocks these days both may be causing higher amount of unconfirmed transaction clogging network.

The number of transactions increases.
Some did (and sometime do) spam attacks on the network and it takes time to clear up after those.
The 1MB limitation doesn't allow to add into a block all the unconfirmed transactions.
Some pools hunt the block reward and don't use the best of the block size to include all the transactions they could.

But it's OK. Those numbers will rise slowly and will force people to use common sense tx fees, not just rely that the network will work for them for free.

yeah this is part of the reason but so far unconfirmed transactions has been only in the range of 2000-3000 and it rarely goes any higher. and these txs are those with 0 fee and low fees, etc.

the 20k-30K unconfirmed transactions has been rare and as you can see the number of unconfirmed transactions has reached half the amount to 10K and decreasing fast.

they always happen when there is no blocks mined in a longer time than usual like an hour with no blocks.

Well, I haven't noticed any delay today. I made a transaction around 30 minutes ago and with transaction fee just slightly over 20,000 sats it took less than 5 minutes to get confirmations.

So I'm wondering are all those delays happening because very low transaction fees were included or you might have a delay even with higher transaction fees?

Well, it's an auction, if you pay high enough fee you'll always beat everybody else, but they cannot all win the auction.

actually just curious a bit why people are so stingy around crypto world,doesn't generalize,it's just a few but they won't even set the fee higher than 5 cents which is actually in 1st tier would couldn't getting used to buy food or you will got only few of candy,even it's for the sake of their transaction speed

I think that today you need at least 10k satoshi to see a transaction get relayed. Just you can still read here and there that 1k would do or you can - with luck - send even without fee. And that doesn't work for quite a while now, from what I know.
But people still use faucets. People still try to send under 1$ worth of Bitcoin from here to there. And for them the 6 cents is quite a big % of "their money".

I also use as low fees as I can, I just never complain of that. I even gave my example not long ago that my transaction took one entire night. But I was OK with that. But if we continue that, at some point the miners will halt their businesses (unless BTC price will get H U G E). So for now, the network enforcing in some way to become correct, is not a bad thing imho.

Thanks for your reply and thanks for the great link, I have bookmarked it because I think it's really helpful. But I can't agree that this is like an auction because in auction only one person wins a lot, so to win you should pay more than others. Here we have a slightly different situation - to be the winners, or in other words to have our transactions confirmed fast, we just shouldn't be among those who is paying much less than others.

It's an auction and there is more than 1 winner because there is more than 1 position being sold...

now a lot of transactions. plus a growing number of blocks. I think it's better to improve miners fee, so bitcoin faster delivery. 

[NeuroticFish]

There are still blocks mined without adding all the possible transactions.

The last number is the size in kB.

The pool software or something needs fixed/optimized along with the increasing tx fees.

That happens when a block is found immediately after the other, I don't know if it can be fixed.

I don't think increasing transaction fee is the answer, this is how cabals take over financial system and will need to understand that you can never satisfy Greed it keeps asking for more, this may be a move by miners to delay moving transactions with low transaction fee.
