OK, that's great! Now, my other question is how do I decide the renting fee? How does renting work? Is there any article for this?
You can set the four rates for renting out your tokens in your dashboard. The rate you set is applied to all of your unused tokens. At the moment, only the lowest rate is rented out to 100%, because there are not a lot of small miners (for which higher rates apply) active at the moment. But this should change when Pods are powered up and smaller miners will join the club.
