No, because they are two different things
Paypal is just a payment processor, which supports many currencies
Bitcoin is a currency, and your wallet a payment processor
In my country for instance, one cannot use paypal because of the risk of fraud so there are things that we cannot purchase online because of it.but with the emergence of bitcoins, we can easily buy the things we want online with the fear of order being fraudulent. So a means of payment in this scenario bitcoin has overcome Paypal.
About which country you are talking about, im curious.
Blockchain does not resolve the problems regarding payment for products.
If the payment is maid, it is not reversible and YES, seller is protected.
But how about the buyer? How buyer can be sure that seller will not scam? There should be 3rd party for assurances or some-kind of block-chain technology that allow to encrypt the deal in such way that buyer has protection also, for example he could release the money himself from some kind of smart wallet when he has satisfied with service.
