Selling Bitcoin in exchange for Paypal payments couldn't be easier. Simply input your Paypal address in this form, click Next and you'll be given a unique code to send the BTC payment to.
The rest happens automatically.
Simply generate your unique payment address, and send as many coins as you'd like to it.
When the payment is verified, BTCPro uses the current rate (taken from the the Bitpay API, listed on this site) to immediately send the value of your coins to your Paypal address. Paypal automatically converts any payment into your local currency.
