Newbies accepting paypal and asking you to chat offsite so they can convince you to send first because paypal is reversible, I would advise you to avoid people like that because they will scam you and you might get your money after 7 days if your lucky, but he will have moved the funds to another account by that time. Always use an escrow when dealing with newbies and you will see if they are scammers or not.
yeah! scammers are every where, like a wolf wearing a sheep like coat to cover their true identity. just beware from them so you wont lose your btc. or much better do, meeting up people who really want your service. dont accept not meeting up.
