I tried to send a bitcoin transfer monday afternoon and it is still unconfirmed. Paid the default fee and the transaction has said high priority since i sent it.Can anyone help me get this confirmed? Would greatly appreciate any help!

The transaction is: https://blockchain.info/tx/907e8e446585be642bf85d89b15a55e306fe9868ed713c0cec84781761bcbd7a

  • Don't rely on blockchain.info notion of 'priority', it is horribly outdated. – Pieter Wuille Nov 22 '16 at 19:45

Your transaction's fee is pretty high and its size is small. It usually should get confirmed right in the next block.

The reason it's still unconfirmed is that there currently is a very big number of unconfirmed transactions. Around 57'000. Usually, it's somewhere around 1'000 to 3'000.

This already happened a few months ago. The mempool back then was 8 MB big. Right now, it's 35 to 43 MB big (depending on who you ask) and a block being mined (which statistically happens every 10 minutes) can only reduce it by about 1 MB.

Inconveniently for you, the size of the mempool has skyrocketed since you made the transaction due increased frequency of transactions.

If it continues like this, the blocksize limit will likely be increased so a block can decrease the mempool by more than 1 MB.

Your fee (0.5907 mBTC/kB) is above the current mempool average (0.2871 mBTC/kB) but there are a lot of transactions with higher fees than yours. Because of this, the miners will pick other transactions instead of yours.

The only thing you can do if you really need the transaction to go through fast is to send it again with a higher fee, this time.

  • Thanks for the reply,how would i be able to send it again? – frostyy Nov 22 '16 at 20:17
  • This is a transaction replacement. Usually, wallets won't let you spend the same coins again (and you want to spend the same ones again so only one of the transactions can eventually get through!) which is why you have to re-import the wallet's data file into the wallet software. The details depend on the wallet you're using but it has been discussed for different wallets on this StackExchange site and all over the internet. – UTF-8 Nov 22 '16 at 20:22
  • Would you recommend doing this or is it just easier to wait it out? And again thank you – frostyy Nov 22 '16 at 20:25
  • You won't lose anything but the time you spend doing it and maybe (only if the second one will be the one to become confirmed) the difference in fee you choose. As long as the second transaction isn't confirmed, the first one is still valid and miners may chose either one. If a miner comes across the second one while already knowing about the first one, they may drop the first one in favor of the second one and then process it faster than they would've processed the first one because the second one has a higher fee. So, yes. If the transaction was important enough for me, I'd do it. – UTF-8 Nov 22 '16 at 20:39
