Bad bad idea. People will buy bitcoins with paypal - you will transfer the coins - and then people will dispute the transaction on paypal and get their money back, leaving with you nothing.
Paypal always sides against bitcoin.
Indeed. One of the many bad ideas op had. This is why new people should not be starting stuff.
I already knew this before he had replied, I am not exactly "new", when I discovered bitcoins you could barely buy a pizza for 10,000btc.
As I said, the user pays for "tokens", withdrawing them from his account would be impossible until a refund will also be impossible, I am not really going to handle the payments systems but this is what I have in mind, the people who handle the payments are not related to us and the information will not be exchanged between us.
