How to do

[marketersales]

I have heard that when you sent an BTC transaction something like 10 BTC for example, you can still chargeback the payment of the transaction dosent have at least 1 confirmations. So what i am telling it is possible to chargeback the payment if it has 0 confirmations? And how to do it? Thank you.

You can't "chargeback" a Bitcoin transaction, ever.

There are ways you can double-spend a 0 confirmation transaction, most of these involve having a lot of mining power (such as the finney attack). There is no easy way to do this though. There is more info here:

Also, the Marketplace is in the wrong section for this.
