For 3 years that i used paypal way back before,i will say that Its not a scam ,cause i have not encounteted one to say that paypal is a scam. Paypal is the most secure online bank before till i met bitcoin.
I also use PayPal for 4 years already and hadn't any problem with this site ever. I even heard today that they work with bitcoin now, is it true?
PayPal has been used for a long by more users from all parts of the world. Till now only very few have encountered some problem with PayPal. In a recent article one of the founder Thiel stated the working with bitcoin for a futuristic development and get more users.
