I recently tried using this website to exchange $100 worth of Bitcoin to USD in my PayPal account.
The problem came when they had numerous customers send me smaller payments to my PayPal and several of them filed disputes with PayPal claiming they did not receive what they paid for.
Even though I immediately refunded their money, PayPal has my account on restriction so I can not access my funds in any way except to issue further refunds.
I am going through their process to resolve the issues, but my hopes are not too high. I think I just locked up the $500 I had in my balance for 180 days.
If you value your PayPal account, I would not risk it.
