Notice the Sticky at the top of this forum?
Hopefully you didn't get scammed for too much in the learning process.
When you want money to end up in your PayPal account, trade your BitCoins for MoneyPak card numbers.
They're cards people can get at local stores for $5 and load cash onto. Your buyer can just send you the numbers over the internet, at which point you can send the BitCoins to him.
You may also want to consider using a third-party as an escrow service. Costs a percentage as a fee, but he holds the BTC or MoneyPak data until told by the other party to give it over. So nobody gets scammed.
lol , I used to do that , until someone called moneypak and opened a dispute. Now they blocked my Account.
