Paypal is even more well known in not so internet savvy country than moneybooker. I guess more people get to know paypal first that's why it's more popular.
@Confused freelancer PayPal indeed more popular than the moneybroker, I already own to create an account moneybroker but almost not in use, because the website is almost paid for using PayPal payment method. Moreover, PayPal now has shares purchased by eBay, one of the reputable international website.-
