I'd choose Bitcoin over Paypal any day. Sorry but Paypal just sucks.
Their buyer protection on ebay is a gigantic fraud as well. I can't understand how this company is still existing.
The company "is still existing" because people use its services. Choosing them over other payment methods available on eBay.
EBay has made itself popular years and years ago and now they are somewhat of a leading marketplace where people are forced to use PayPal as main payment option.
And nothing will change as the average user has not much problems at all with PayPal as they are buyer protected.
The only way to stop PayPal is to make the majority of its users stop using it, otherwise nothing will change.
