True, If the person you tried to trade file a dispute against you then for all you know you can't bring your BTC back to you. I think that if PayPal finds out you trade funds btc to paypal most likely the person with paypal dispute win.
That's why hindi iniencourage ang BTC to Paypal exchange transaction dito sa forum.
But it doesn't mean na di na talaga pwede mag exchange using paypal, it's all about risk. If you can observe most trusted person dito sa forum is nakikipag exchange parin through paypal with BTC kase nga dun sila nakkipag transact those people na trusted.
If there's a chance na ireverse yung transaction through paypal then red trust is on the way para diyan, iwan ko lang if merong high trusted profile na mag gaganyan except na lang sa mga newbies or ranks below sr members.
