Before I get negative feedback from Vod, yes, these keys are illegally obtained, and they may or may not stop working and I may or may not keep my replacement guarantees as he points out on all the other sellers on here as well. Actually, I am not trying to rip off people like those who come here with 10 day old accounts and have 5-10 contacts on their newly made Skypes.

If you're interested, send me a PM or Skype me: vurezo

Selling in bulk, can split trade up to 10-20-30 parts, however many you feel like, so no middleman required. Minimum selling 50 keys at a time. (Which I can split up into many smaller trades for your convenience.)

All the accusations thrown against you are total bollocks, I've been a long time seller myself and it costs me close to nothing to keep my refund guarantee, and it wouldn't cost OP much either. Most of the time when it's in regards to refunds, it's mostly human error as you sometimes need very specific ISO files and such, or activate the key before installing service packs and such.

Thanks for supporting me. I appreciate it big time mate.

I don't know why people are so butthurt about this. I just bought a Windows 8.1 key and it worked flawlessly!

Personally I don't care if it stops working after a year or what not, for 5 bucks I have genuine install of windows with no crappy KMS service or any kind of malware dumped into it like the popular torrented ISOs.

I recommended your website to my friends so they can get off crappy pirated versions and finally have a real version of office, etc. Keep it up!
Yeah, exactly, and if it by some chance stopped working, you can just ask OP for a new key as per his refund guarantee. In my experience, after I had an invite get banned, the keys that were already activated continued to work. I've only had to replace a 2-3 keys in the few years I've been somewhat active. The way I got my invite banned is a funny story actually, I sold a key on Ebay and the buyer was a black guy who was the head of Microsoft anti fraud as I googled his name after my Ebay getting banned.

52  Bitcoin / Development & Technical Discussion / Re: Double Spending 101? on: February 27, 2015, 02:58:48 PM
I was looking for more practically speaking kind of information if anyone has any. Thanks anyhow, it was a good read, although I've read it already.
53  Bitcoin / Development & Technical Discussion / Double Spending 101? on: February 27, 2015, 02:47:57 PM
Not trying to rip someone off here, recently had a situation where double spending saved the day.

My question is, what is the best way of double spending? (I have almost no clue what I'm talking about, please keep that in mind.)

Sending any amount without fees to 2nd address, then spend from 2nd address and resend from 1st address to a 3rd address with fee? (Would it then pick up the 0 fee transaction if transactions on 2nd address were made with fee (although input is still unconfirmed?))

Spending minimal amount without fees to 2nd address, where some additional coins gets sent back to yourself, which should make it minimal priority since it's so small, then send whole balance including the few unconfirmed ones that got sent back to yourself to 2nd address, then send new transaction with whole balance with fee to 3rd address?

I'm also thinking, if there's some reliable way to do this, maybe quite a few scams could be prevented by preemptively setting up a double spend scenario with a potential seller so that you have the option to chargeback if he turns out to be a scammer?

-snip-
OP just went to bed and he's new to BitCoins, if you could, please PM him your Skype or whatnot, any help is greatly appreciated. If not, I'll try my best to help him and probably make more of a mess than the one he's already in!

In that case its probably best to let them sleep. Time is essentially on "our" site as it improves the chance that the transaction gets confirmed and the chance that nodes forget about the transaction. I dont use skype and I am afraid I know of no safe way to help remotly that would not compromise the private key. I could write step by step instructions how to export the private key from bc.i into bitcoin core/qt if that helps.
Sure, anything will help. I didn't quite understand the steps, do you want him to paste all that into the console as-is or paste the main commands and replace the rest of the command with the output?

Anyhow, it wouldn't be the end of the world if his private key got compromised, as he's going to be changing to an offline wallet after this incident. I hope I made it clear that everyone who has received unconfirmed funds needs to be double spent to get confirmed funds or whatnot. (i.e. https://blockchain.info/address/16rKfUnTnSiFdqRA3j69XNdfKwSBNxF5wX all nine of those unconfirmed ones.)
55  Bitcoin / Bitcoin Technical Support / Re: How do I double spend? on: February 22, 2015, 12:49:40 PM
I think it will be tricky as one depends on the other unconfirmed.

How to create a raw transaction: https://www.reddit.com/r/Bitcoin/comments/2ebaow/how_to_create_a_raw_transaction_in_bitcoin_qt/  It's for Bitcoin Core, so you'd have to import your private key there. You would have to look for the original unspent inputs on the blockchain.

The thing is that you then have to submit it to a pool who can include that double spend in a block for you. I think f2pool are the only ones offering it publicly, but you still need to contact them before hand.

The alternative would be to wait (maybe a week or so) for the network to forget that tx and then send afresh, with appropriate fees. Or maybe it even confirms in the meanwhile.

I just had the same idea and checked, neither my server, nor my desktop node[1] know about the transaction. Even bc.i's pushtx service[2] can not decode the transaction (which usually indicates that its not in their mempool). Creating a raw transaction might indeed do the trick. Once its signed you can post it here and we can help broadcasting it.

[1]
[2] https://blockchain.info/pushtx


Edit: does bc.i allow signing a rawtransaction? This would allow you (Newar) or me or someone else to create the rawtransaction (unsigned ofc) and let it get signed by OP via bc.i. If its possible, is it safe or would that allow a known plaintext attack on the private key? Nope


Edit2:

The inputs are from these 4 transactions:
https://blockchain.info/tx/9ae64385748ca866ce4ec29824e517a49346bae05b4816706d5dc50a0bb9d5ac
https://blockchain.info/tx/536ec9ad154d8b3491c7dcd2cfac88e8a7d49c3d3d6969c627ca7358ee5a555f
https://blockchain.info/tx/540dce68990db42bf281a76dbce659483b5810a8413f0067a715c30e41c62e67

Thus this:

Code:
createrawtransaction
"[
{\"txid\":\"9ae64385748ca866ce4ec29824e517a49346bae05b4816706d5dc50a0bb9d5ac\",\"vout\":1},
{\"txid\":\"536ec9ad154d8b3491c7dcd2cfac88e8a7d49c3d3d6969c627ca7358ee5a555f\",\"vout\":1},
{\"txid\":\"540dce68990db42bf281a76dbce659483b5810a8413f0067a715c30e41c62e67\",\"vout\":1},
{\"txid\":\"770ac18545282258eac4e463900beb7601a9158b255da3a185f292b7b3c28698\",\"vout\":1}
]"
"{\"16rKfUnTnSiFdqRA3j69XNdfKwSBNxF5wX\":0.21042297}"

Would create an unsigned transaction that spends these 4 inputs and pays a 20k satoshi fee.

It returns the raw and unsigned transaction
Code:
0100000004acd5b90b0ac55d6d7016485be0ba4693a417e52498c24ece66a88c748543e69a0100000000ffffffff5f555aee5873ca27c669693d3d9cd4a7e888accfd2dcc791348b4d15adc96e530100000000ffffffff672ec6410ec315a767003f41a810583b4859e6bc6da781f22bb40d9968ce0d540100000000ffffffff9886c2b3b792f285a1a35d258b15a90176eb0b9063e4c4ea5822284585c10a770100000000ffffffff0179144101000000001976a914402c972aa8932483ba216d3ce1f4ee5f2e35ea8988ac00000000

which decodes to:

Code:

Thus bitcoin core/qt (even unsycned) should be able to sign it with:

Code:

Please, please, please OP, before you do this let someone else (preferably yourself after understanding what I did) confirm that I have not made a mistake.

OP just went to bed and he's new to BitCoins, if you could, please PM him your Skype or whatnot, any help is greatly appreciated. If not, I'll try my best to help him and probably make more of a mess than the one he's already in!

OP wants to fix all the unconfirmed transactions to make sure everyone gets their money.  Roll Eyes
57  Bitcoin / Bitcoin Technical Support / Re: How do I double spend? on: February 22, 2015, 11:31:02 AM
On OP's two latest transactions (with a HEAVY miner's fee paid), it says that he has unspent input, and when I checked his recieved, all of his received funds are confirmed?

Edit: Unless it's trying to spend funds of the funds that were sent back to his own address from within the unconfirmed transactions...
58  Bitcoin / Bitcoin Technical Support / Re: How do I double spend? on: February 22, 2015, 11:22:04 AM
OP does, he needs to get his wallet fixed, can anyone help us?
59  Bitcoin / Bitcoin Technical Support / Re: How do I double spend? on: February 22, 2015, 11:13:38 AM
How do I perform a double spend attack, as I received some funds without the guy paying a fee,

You can only create a (new) transaction for funds you have the private keys for. Since you received coins it is unlikely that you have the private keys required to create a competing transaction with fee.

and now I just want to spend the funds I have that is confirmed

So its confirmed?

but I can't because the transaction sent money to itself which included the money which was unconfirmed

You lost me. A single transaction can not be confirmed and unconfirmed at the same time. Maybe if you can give more detailed information in a clearer way someone here might be able to answer your questions. You could also just post a transaction ID.
He actually does, he's the sender of the unconfirmed funds and he's posting on my friends behalf. As you can see, there's one transaction received with unconfirmed funds, so we sent all the confirmed funds (minus miner's fee) to another wallet, but it won't go through as you can see, it's also unconfirmed.
