Metcalfe’s law, the bitcoin, the ethereum and their value. I am a Data Scientist student and I took a course with Dr. Fragkiskos Papadopoulos on Network Science.

It suggested that the value of a service is proportional to the number of connections it can create, which is the square of the number of its users. In contrast the cost grows only linearly with N. Hence if the service attracts sufficient number of users, it will inevitably become profitable, as N² will surpass N at some large N (Figure 1).
