Faucet sites, is it worth the effort?

For all the faucet users out there - I did a little math before deciding continuing use of the free roll sites. I am forced to think that the effort spent does not justify the earnings.

Assumptions: -
 - Most sites allow 1 roll per hour
-  On an average per day, you will be able to make 6 rolls

Case 1: - if a person has ZERO referrals and does the rolling only for self
Case 2: - 10 referrals signing up and actively earning the referrer 10% (on a daily basis) + self rolling 6 times/day

Foot note: 
1. This math is limited to sites where only 'free roll' is performed. ex. https://free-doge.com/. There are surveys to earn additional crypto but I have not tried it yet as brave does not allow the sites to load. So no comments on that.
2. so far - I like the sites where hourly/periodic claim + PTC ads + short links are available to be used as well.
