What exactly are chargebacks and chargeback fraud?
Is it a complaint about not receiving the product, or is it about the customer saying that he did not authorize the payment?
If I understand correctly, it is about the second one and therefore some claims that there are no real best practices to adopt in order to totally avoid it.
So what's left?
What could another chargeback-free payment option be (beside BTCs) when you're selling goods or services with a high risk (high-cost products\services)?
