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.

[4:45:30 PM] Owsla: whats that

lmfaooooooooooooooo

 

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)

 

lmao this dude tried to scam me this same way earlier for 130 dollars.

 

I used coinbase and my last transaction took almost 2 hours before the first confirm..
