I am not sure about it but I heard that some Chinese bitcoin users are cashing out their bitcoins (probably because of their bank's statement) and thus it brought load on the blockchain which is causing the delay in transaction confirmation. If you have very urgent transaction then include double fees than usual and it will probably work (It worked for me).

Slowly but surely. Mine take 7 hours because I only include very little fee but not to little that it might not be confirmed. Also, Bitcoins I received on my Xapo are instant compared to my coinbase or blockhain

I never get slow confirmations if I pay the recommended fee. That one gets confirmed in maximum one hour. If I go under the recommended fees, it can take even two days to get it confirmed. And compared to other payment methods (like bank wires), it actually doesn't really take too much time. I would rather wait one hour than days for one payment to be sent ..

Lucky you, I use blockchain info basically they implemented a dynamic fee structure where they set up the fee for you depends on network traffic, if there are more network traffic it means the fees go up while less network traffic then the fees are lower. However with their feature my transaction always got stucked almost 1 days, i truly believe that i paid recommended fees, i didn't understand why it took too much time for confirmation.
In order to get fast confirmation, sometimes i increase the fee or transaction with bitcoin debit card.

To make the transaction much faster is to pay higher miner fees. That way you will get confirmation faster than others. And another thing it is true that blockchain.info wallets has faster transactions. I am playing bitsler and when I withdraw I use blockchain.info wallets then in just a matter of seconds to 1 minute the balance is already in my wallet.

the same, I also experienced for sent btc to exchanges is taking much time
Maybe the miner is so busy, so we need raise the fee for fast confirmation.

If everybody pays double, then we end up in the same situation, and everybody will be saying pay quadruple.

The number of people complaining about this problem has increased significantly in recent weeks. At first I thought that some individuals were trying to create FUD, but then I realized that in fact there are many users facing this problem. The scaling issue is something serious, and I would like to see this resolved this year.

I also had the same experience with Blockchain a few days ago.
I chose recommended fee and send one payment but had to wait more than 24 hours for transaction to be confirmed.
I didn't have small fee, not at all.
So, I really hope that this situation will change or some people may give up from Blockchain, because of very slow confirmation process.
