I think the reward system really helps out if you have a lot of time to continue building your faucet earnings. You can both make your earnings a lot more if you want but you can also make rewards a lot more as well. So maybe you can do like 6 days of reward building with your rewards and increase your reward points and than use that 1 day to make your earnings more and keep doing that everyday, if you have the time of course. That would not only increase your rewards but also your available amount which can get interest just by sitting there.
Utilizing the reward system for the optimum best income could make one earn a lot more, no matter how much time you have. There are people who use like 20 times a day and those people with right utilization of reward system both can get richer and claim much better rewards as well.
