    Failed Bitcoin Double Spending - Wait at least 1 confirmation

    Someone just sent me a fake bitcoin transaction, keep an eye out folks, wait at least 1 confirmation before assuming everything is OK.

    Double spender was using the following skype: live.gaoying0102 & jaywalker2291

    Here is a link to the blockchain info: Bitcoin Address 1DtG4TJjfcNAanTSuZqLzswHzC1vrvKQ56

    Their address: 18fkmuxAqAQsCgYMApmfnpvY8qYPX434Cr

    My address: 1DtG4TJjfcNAanTSuZqLzswHzC1vrvKQ56


    They claimed to be using coinbase, but the transaction fee on this transaction is much lower than what coinbase pays for their transsfer. If you look at the transaction id: Bitcoin Transaction aad5e044d19827a59d5da57aad6d5d5e1c03827c6dc6b724198307cf06e1434d

    You'll see this was sent with a $0.00 fee. Coinbase usually sends transaction with about $0.25 fee which helps them process faster. The lower the fee, the slower the transaction can be confirmed on the bitcoin network, the easier it is to double spend bitcoin.

    Wait at least 1 confirmation unless you can afford to lose whatever you're exchanging for bitcoin.

    This scammer had a plan A scam and plan B scam. Plan A was to try to get me to give him the runescape gold BEFORE the transaction confirmed. Once he saw I wasn't doing that, he asked for a refund on the bitcoin. He wanted me to send him the same amount of bitcoin he supposedly sent.

    [1:19 PM] LooneyToon : I've copied the chat log for your viewing pleasure:

    [4:23:49 PM] Owsla: How longs it take usually? thought its meant to be instant send on coinbase
    [4:24:34 PM] LooneyToon : yeah sends instantly, but it has to be confirmed on the bitcoin network 6 times to be authenticated. Usually takes about 15 minutes for the 1st confirmation
    [4:24:44 PM] Owsla: oh right
    [4:24:50 PM] Owsla: hopefully its not long
    [4:25:01 PM] LooneyToon : you used coinbase to send it?

    [4:25:11 PM] LooneyToon : should be pretty quick then
    [4:25:20 PM] Owsla: hope so, gotta leave soon :p
    [4:25:42 PM] LooneyToon : if you have to leave before I give you the gold do you want me to refund the btc or hold onto the gold?
    [4:25:58 PM] Owsla: uhh just refund
    [4:26:08 PM] LooneyToon : ok, hopefully we wont have to worry about that
    [4:26:12 PM] Owsla: ya hope not
    [4:26:26 PM] LooneyToon : are you familiar with blockchain?
    [4:26:35 PM] Owsla: uhh no whats that
    [4:27:08 PM] LooneyToon : if you copy the address that you sent bitcoin to, go to blockchain.info and paste it into their search bar
    [4:27:22 PM] LooneyToon : you can refresh that screen and eventually it will show you when the transaction has been confirmed
    [4:27:39 PM] Owsla: ok
    [4:27:43 PM] Owsla: ill have a look
    [4:28:38 PM] LooneyToon : heres the link Bitcoin Address 1DtG4TJjfcNAanTSuZqLzswHzC1vrvKQ56

    [4:31:34 PM] Owsla: this 1 was it
    [4:31:36 PM] LooneyToon : the lower the transfer fee, the slower the transaction
    [4:31:42 PM] LooneyToon : the higher the fee, the faster
    [4:31:44 PM] Owsla: 2777 minutes :D
    [4:31:45 PM] LooneyToon : coinbase uses high fees
    [4:31:47 PM] LooneyToon : WOOW
    [4:32:19 PM] LooneyToon : that is crazy
    [4:32:27 PM] Owsla: yea, lol.
    [4:32:27 PM] LooneyToon : so far i havent had any of my transactions take over 30 mins
    [4:32:30 PM] LooneyToon : usually 10-15
    [4:32:39 PM] LooneyToon : sometimes just 5 mins

    I didn't know this was even a thing until yesterday. Sometimes confirmations take hours so waiting for first confirmation isn't something people are okah with.

    I now ask my buyers how they are sending their bitcoin. In my experience, if they're using either coinbase or circle the transaction confirms within 15-30 minutes. You can check the transaction ID number and see exactly how much transactions fees were paid.

    If you're buyer is using their own wallet application like bitcoin core, they have the ability to increase or decrease the transaction fee amount. Hopefully they are competent and are able to increase the transaction fee so it confirms faster.

    (I dont really know what I'm talking about, learning as I go)
