It has been said sometimes that a Bitcoin transaction can be cancelled or reversed using for example double-spend.
Is it still possible? If Yes, how? If No, Why?
Especially when you sell services and goods and accept Bitcoin payment, you are worried about this.
So it should be a good idea to discuss this topic.
No, because in my opinion although using the double shopping method to cancel it is not possible because it will definitely be processed quickly one by one and cannot be canceled. and of course when we cancel it requires a process but the bitcoin transaction continues.
the solution is we must be careful before doing something not random.
