Bitcoin has a lot of potential, but replacing the US dollar is a different story. The dollar isn't just a currency — it's a global reserve, a store of value, and a tool for international trade. It's deeply embedded in the financial system. Bitcoin is still too volatile, too slow, and too niche to handle the scale and stability the dollar provides. Plus, governments aren't going to let their currency be replaced by something they can't control. It's not about whether Bitcoin is good — it's about whether it can meet the needs of a system that's been built around the dollar for decades.
