100% bitcoin is much better than paypal,
In paypal you have to disclose all you identitys and you have to give your identity proofs , in paypal transaction reverse is very famous to scam. and i personally saw paypal and the procedure of it is very bad. and their charges also heavy.
In bitcoin you dont have to disclose your identitys , you can just create a hardware or online web wallet and give your wallet address where ever you want to receive or pay the bitcoins. the transaction charges are also less. and more it is irreversible, and about converting to fiat currency their are so many exchanges where you can convert it one is like localbitcoins.com which is having so many user who are ready to buy or sell and do transaction through bank transfer.
Bitcoins better than paypal off cours not because i know where to use them both for off course. There are so many people who dont like to use bitcoins but like to use paypal.
Well there are people that still love paypal and they use it regularly on purchasing online instead of bitcoin but as we all know that bitcoin adoption is not yet reached in any corners in the world and some are not yet informed or awared on the bitcoin existence but if they know the accessibility of bitcoin and transaction process maybe they would definitely switch to bitcoins.
