If I memorize the word greenzap clearly,It was an online buying and spending account service that claimed to compete with PayPal. GreenZap was launched on April 2, 2005 and allowed members to send and receive money online, through their email address. The ultimate beneficial owner of GreenZap was reported to be Damon West moreland, who was reportedly associated with ThePayline.com,a widespread Internet financial pyramid. The ownership of GreenZap was unclear because the company was not registered to do business in California, where its mailing address was located in a postal box within a grocery store, and because the company's official phone number was a mobile phone.
So it a scam site and better to stay away from Greenzap.
