I have a PayPal debit card too. The benefit of Virwox is that you don't have to deal with other human beings and the possibility they might be having a bad day and just dispute for the hell of it, or worse as a pre-planned scam strategy. Virwox has been around for a while. It was originally the resource used by Sims users who actually make a living on the virtual platform through something known as Linden dollars (SL). Back when bitcoin was still being newly adopted and exchanges required complicated verification processes, there was no feasible way to conveniently buy bitcoin with PayPal. Of course there were many people who wanted to be able to do it, so Virwox enabled people to go on their site and buy Linden Dollars (SL) and then send those dollars to different virtual games. Virwox found its niche when it decided to allow people to exchange SL for BTC.

Now, long after they discontinued allowing people to send SL to Sims, they still work as a BTC exchange, but of course you are paying three fees. One for the exchange from BTC to SL, one for SL to US and then the paypal fee when you withdraw. 

The entire process takes about 60 seconds and there is no fear of possible dispute or charge back.
