What is the best way to buy BTC using paypal?? is there any btc broker accepting paypal?
Generally no, if there are people taking paypal as payment then they will charge a lot for it. Usually paypal payments are easily reversible that is why a lot of bitcoin sellers avoid accepting paypal payments. There are some that does, but probably you will have to pay 10% - 50% (maybe even 100%) more than the current market price of bitcoins.
That's true. Paypal isn't recommended option for buying Bitcoins. Reason A is that Paypal doesn't endorse buying cryptocurrencies with balance. So selling party will always be on loosing site in case of one party opens dispute.
Reason B is that present merchants providing such exchange is very low and doing so on their own risk. So there is high chance of getting scammed. Better find other ways buying Bitcoins. Closest substitute can be Payza.
