It's possible to dispute paypal payments for up to 45 days, so you'll need a trading history at least that long before people will trust you.
You've been here for 2 weeks.
Yeah. Please don't trade, you most likely will be coming to scammer accusations to bitch about how you just got scammed out of $200.
OP, please use another payment method. If you're paying from a credit card, try btcQuick (they are legit!)
