I would also recommend that you stay away from Paypal like all the other people on that website is saying. Paypal freezes your funds for 180 days for unknown reasons. You could always exchange your Paypal funds into Bitcoin funds in the Currency exchange board. So, if you don't want somebody disputing their payments to you, or getting your account frozen for 6 months, then go ahead and convert all your Paypal funds into Bitcoin.
And I have never had a problem with Paypal. I trust them more than a Bitcoin. How many years in the market Paypal and how much is Bitcoin?
Paypal and eBay worked together to make sure that no one got shafted on either end and I even sold a few things back then and Paypal ate the charges on one sale so that both the buyer and myself were happy.
