I see that most people are scammed in paypal deals but also in bitcoin but less. I consider bitcoin better than paypal in some cases and paypal better in some other cases(for fast deal and buyer protection)
paypal is good with refund system for buyer protection, but this system is bad for seller
sometimes buyer receive his digital good and try to refund his paypal transaction
Yes but the same thing applies for bitcoin right. The seller can scam leaving the buyer without any form of protection..
