If one is selling only non-physical / digital products, then nowadays it is safer to accept only payments such as crypto, etc (on which chargebacks cannot be initiated), if not, then be ready to do a lot of free charity work, because people are now fully aware that incase of card payments, Paypal, etc, incase a buyer has bought a non-physical / digital product using card payment, Paypal, and and even after receiving the non-physical / digital product in good condition, incase the buyer opens a dispute, then nowadays, always, the card issuer, Paypal will favour the buyer only, as the product is a non-physical / digital product. Unfortunately, card issuers and Paypal feel that all non-physical / digital products are defective. This is the reality. And this is why more and more sellers of non-physical / digital product are nowadays only accepting payments such as crypto, etc (on which chargebacks cannot be initiated).
Accept card payments, Paypal, ONLY if your product is a physical product which is physically shipped and you get a trackable proof of shipment.
If a buyer or potential buyer has trust in you and your service, then he or she will not at all hesitate to pay in crypto (nowadays all of us using the internet are familiar with crypto, it is no more something new or something mysterious).
