Hi i want help to know how sell BTC on ebay to don't get chargeback from Scam?
Because i sell some of my btc and i get chargeback from them.
What rules can i learn to don't get chargeback and to prove the paypal that is a scam
My one alternative is to sell with a small item like pen for example and get tracking number is a good alternative to not get scam from buyers??
