This case is mostly interviewer-led. It consists of two questions used to guide the interviewee.
Bitcoin has become the undisputed leader in the crypto market. However, it has also become a "hot topic" because of its negative impact on the environment.

Assuming the client wants to build a solar plant, what is the maximum amount we can invest in this plant to make our plan profitable (i.e. keep our current margin)?
Considering the numerical results obtained, what could be the recommendation for the client?
