HOW MUCH you could earn with one company

This example refers to alladvantage.com - which I think has the best offer at the moment.

Alladvantage.com pay you half a dollar or $.50 for every hour you are online. Not only that, if you refer a friend to them, alladvantage will pay you $.10 for every hour your friend is online. If your friend refers someone, you get an extra $.05 for every hour that person is online, and so on. The small catch is that you can only get paid for 25 hours of online time a month - however, with all your referrals, potentially you could earn quite a tidy sum!

Here's an example: you browse for 25 hours in one month, you refer five of your friends who browse the same amount of time, they each refer 2 of their friends each, they in turn refer 2 of their friends each, and so on like the diagram below.

YOU	5 direct referrals	10 extended referrals (1)	20 extended referrals (2)	40 extended referrals (3)	80 extended referrals (4)
THE HOURLY RATE YOU'RE PAID WHEN YOUR REFERRALS ARE ONLINE
$0.50	$0.10	$0.05	$0.05	$0.05	$0.05

In total, this includes
- you browsing for 25 hours  =    $12.50
- your 5 direct referrals browsing for 25 hours  =  $12.50
- your 150 extended referrals browsing for 25 hours  =  $187.50

A TOTAL OF $212.50 a month --- not bad for 25 hours of surfing!
And you could have even more referrals than this!
