Look, I understand why people are drawn to it — there's something romantic about a system that doesn't need the government or the bank to function, and in Brazil especially, after watching our currency get gutted and our savings evaporate, I get the appeal. But I'm skeptical because I've lived through enough schemes where someone promises liberation through a technology that only works if you already have money to put in. My students ask me about Bitcoin like it's the future, and I ask them: who gets rich when it goes up, and who loses their phone credit when it crashes? The environmental cost makes me angry — we're burning electricity in a country where teachers have to choose between eating and buying chalk. If there's something real here, it should work for a street vendor in the periphery, not just for tech bros in Brooklyn. So show me that, and we'll talk.
