The only good thing about paypal is that it protects well its consumers and the dispute over the charge back mostly the consumers win over it.
Bitcoin is just based on trust if you are going to buy something on an online shop so if its consumer protection paypal wins it.
Yes thats the good thing in paypal they give protection to their costumer and ifbyou get scam using paypal you can file dispute and chance to get your money back. And in bitcoin you can be think twice in investing because if you get scam you cannot get your money back because theirs no dispute bitcoin in bitcoin. And also you can buy items in online stores with paypal but you cant buy items with bitcoin.
