Unconfirmed transaction

[vfilchef]

I by mistake send transaction without fee and he now is unconfirmed.
It is possible to increase fee for this transaction or cancel it?
I see long time ago somebody was posting how to increase fee using blokcain.info but I don't remember how and don't find with search.

No you can't cancel it, just wait it will take a long time for confirmed that transaction a day or more.

Can you post the txid here ?

Can't you double spend the input you used to create the first transaction?

Use the same input to create a transaction with a fee, maybe send it to your own wallet, wait untill it's confirmed, then recreate the transaction you were initially trying to create?

Well, now u'll have to wait for few days and then the network should either confirm it or reject it and send it back to you.

P.S. How about moving this thread to T.S. board?

You need to be very careful. This happens to me as well when I was a newbie.
2 Years ago around 0.00001 was enough, but at the moment you should use at least 0.001 to be on the safe side.
Even with that you could have waiting times. One week ago I have waited 3 hours for confirmation even with 0.0001 BTC.
It could be quite a pain if you are in a rush right now.

The problem is not your TX, but the TX is depends on.

This one -> https://blockchain.info/de/tx/a4062b18bde640d9e0ee6dc3a742f0d2344e1a82f7c1a74b237d0c18b0d49a7e

it pays no fee, but you might get it confirmed if you rebroadcast it every ~30 minutes. You will need the raw transaction

here:

Code:

and either a full node

Code:

bitcoin-cli sendrawtransaction 0100000001ef7a285553b9c606df201f32b826c998caf57bf9369a103852b1a94b163d16d0010000008a4730440220254b9ae2d422029cc2ce41cc84fdfaab10de7a684e68a997567864d9dff3f87502205547685a2421103a8632931ea92b8cb2be1d54df4944f2e896dc270210d32c1801410407099d04a1437fb2a28e50dae5fa4b1c8ba52fdb1dd65cf7d27178f66fee6bafa62fe02378346e5ee651007d25f656f71d2e50c749b1b7e5905efb6c55ca8bbcffffffff0280b34810000000001976a9147156f4b20e0e3ddfa4391154cbf47896a2fa8c9588ac8057220b000000001976a91467513dce408e1005fb4ceeaa8be5726e543a25b488ac00000000

or another interface to do so.

Here is a collection of services that have such an interface.
