Despite its 12 years of age, a consensus has yet to be reached on Bitcoin (uppercase B, the protocol, network, system, or even "ecosystem"), and bitcoin (lowercase b, the unit) - about what they are, what they should be, and what they could become. There are currents of thought, and there is a battle that has already begun to shape its trajectory and use.

Some will be actors in this battle, others observers, others commentators, others victims, but ultimately it could end up affecting everyone depending on the trajectory and exogenous factors like geopolitics or economic crises. What is the real innovation in bitcoin? What are the obvious and major applications of bitcoin technology? What geopolitical prospects could impact crypto and bitcoin? Is the emergence of a new monetary system plausible? If so, which are the candidates? What conclusions can we make about bitcoin technology and bitcoin?
