In the second part of the analysis, we can see in the first chart how the total fees and total users have changed over time. We can see how the total users have been increased over time, however, the fees remain constant, so it seems like users are paying more fees by time.
Finally, the last bar chart shows the global weekly fees by the pool where we can see what happens when a new pool is added. Analyzing each factor, we can see how when a pool is added, appears in the chart in a smooth line during some weeks, but after X weeks, the fees increased heavily (may be because of mass adoption).
