Bitcoin represents a quantum leap in the evolution of the internet and open-source technology. Shifting the base of control from unpredictable people to predictable math.
Furthermore, an international currency would improve trade and bring countries closer. Disputes over borders could be minimized, and the unbanked could participate in the global economy without the interference of proprietary 3rd parties.
Bitcoin enables peer-to-peer transactions without the need to go through any intermediaries. Moreover, these transactions are instantaneous when using the lightning network and unbound by political borders.
