Hi Guys! i have a big problem...
2 days ago i sent a transaction that has been rebroadcasted and the btc was send to my wallet but on Blockchain the transactions it's still there:
https://blockchain.info/it/tx/31477301b2c7e819cf2723a8166e5ed7ecf52efbba3399fcd48ca661b6cecf5d

And when i tried to make this new transaction:

e8c15b5919384ec5b29eb1f98c3cab09055a4fdb0249bec8b4194481ddfcba97

Electrum sent the BTC but i didn't see the transaction on any bitcoin block checker..
What can i do?

P.s i've heard about "Double Spending" what is? Can someone please link me a good topic that explains why and how to do it?

Thanks

Simple explanation is you sent it with less fee that what is required to get your transaction get confiremd fast which is an atleast 90 sats/b, your transaction only have 50.224 sat/B . I checked the blockchain link you provided and it is there. If the transaction you sent is not showing on block explorer then it means that it has been dropped in their node.

Hi Jace, Thanks for the informations.
Can you please tell me if the transaction get dropped what happens?

I just pushed your transaction through https://www.viabtc.com/tools/txaccelerator/ should confirm within a few hours

If you are using Electrum use the latest version, make sure you have dynamic fees AND replace by fee (RBF) enabled. When you send set the fee slider all the way up to HIGH and also check the replaceable box. That way if your transaction is taking too long to confirm you can just click on it and bump the fee up.

From what I heard from others it will be returned in your wallet once every node dropped it. The other guy accelerated your transaction and may have helped. If still not confirmed try contacting quickseller to help you with the problem. Here is his profile: https://bitcointalk.org/index.php?action=pm;sa=send;u=358020

ViaBTC reported acceleration successful so the next block they mine should confirm the transaction.
