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.
If you are a true potential bitcoin user you must know that there is no such as better to use you know paypal is good for online payments bitcoins also but whwat you have to do with the
bitcoin is not paying online you need to invest with it or atleast buy things with it.
