I have worked a lot with exchanging e-currencies for certain niche reasons. Exchanging can be quite a pain. Generally you have to tap into the various exchange communities to figure out your options and lookup reputable exchangers. In these communities you will find that a widely accepted rule is that you don't exchange with currencies which allow charge backs (unless perhaps you personally know that person.) That includes Paypal and credit cards.

Yes, there are people who will exchange for Paypal and credit cards. Yes, there are some services which can start out with low charge back rates. The problem is the scammers will find you as the service grows. This is a business with low margins, eventually you will lose out.

Again, Paypal isn't perfect, but the service has plenty of experience with this issue. Too many people are getting screwed over. Unfortunately this is a lesson that people have to learn over and over again. Do NOT use Paypal for exchange.

I don't understand why I'm getting down voted for this.
