Topic: how to cancel a transaction (Read 1009 times)
I am really interested! Sending a PM..
Is double spending possible through a blockchain.info wallet? This double spending thing looks really interesting 
Teach me more xD
Double spending is when a person broadcast two seperate transactions which spends the same outputs. Since the majority of the network runs Bitcoin Core, the reference client, they would first receive the first transaction and store it in their mempool. The other transaction will then be rejected. It is fairly hard to attempt to doublespend the transaction on the blockchain but it can be accomplished. If you have a transaction which has low fees, wait till most of the peers drops your transaction in the mempool then you can broadcast it again. Blockchain.info used to have a page to allow people to test it out but it's removed already. There are also some open sourced programs that allows you to double spend but I can't guarantee it is safe since you have to give your private key.Teach me more xD
Blockchain.info seems to be rebroadcasting your transaction whenever it gets dropped out of mempool. Get the private key and delete it out from your blockchain.info, store it somewhere safe then wait for a week. After that, verify that it has dropped out of the mempool and import it to a desktop client to send the BTC. That's what I have done before anyway.
try deleting the transaction.

Just give it time it will go through, even without a transaction fee. At least it was only 10,000 satoshi.
My longest pending transaction due to little to no mining fee took about 2 months to get confirmed.
As Jose mentioned you could try a double spend, which once confirmed will essentially cancel out the transaction you sent.

blockchain.info online wallet. how to do that double spend? the transaction im asking is in cycle for a week now :/
And there is no option to cancel it on blockchain.info? if not, you could export the private key for the Bitcoin address you sent from and import it into another client (or fresh blockchain.info wallet) and make another transaction that moves all of the bitcoin out of it.
thank you.. ill try to remove those addresses from my blockchain wallet for now and wait 1 week more before i check that the transaction is really cancelled and wont start automatic sending a no fee transaction

How do you exactly double spend Bitcoins? I always wonder.. 
I ever do a mistake like OP doso I create another transaction with same input, with fees this time.
The old one without fees never confirmed and forgotten from network, and the new one successfull sent the bitcoin
ahh i see.. i know that thing, but in my case, it automatically sends another transaction(no fees) when the original transaction gets cancelled.
What is your wallet?

i know it sounds odd but ill start my question here, my problem is in my wallet, i tried sending 10k satoshi from address "A" to address "B" without transaction fee, it takes days and it automatically cancelled but when it cancelled it automatically sends 10k satoshi again from address "A" to address "B".. any suggestion how can i stop this cycle? i cant use my funds left in those addresses
