Honeygain is a service that will pay you for your excess bandwidth. You just install it on your computers or mobile devices and it will detect when the system is idle. From there it will utilize your extra bandwidth and reward you based on what it uses. After a week of running it, here is my following output and the amount I have earned on an account with higher speeds than my last review.

2/1 - 4GB

2/2 - 1GB

2/3 - 1GB

2/4 - 1GB

2/5 - 1GB

2/6 - 1GB

2/7 - 1GB

2/8 - 1GB

2/9 - 1GB

2/10 - 1GB

Total value of the data is : $1.23 

I will say this was on a test laptop with a wifi attached to a 30MB cellular hotspot connection. This was a second account I was running on a separate network. I am noticing on both accounts, the first day certainly used more data. However, each day after seemed consistent in using 1GB/day in data. This went up on my other account when I added additional devices. So, I'm going to say this one is intentionally limited. I am also seeing less than $.10/GB of data. However, it seems to be close.
