The “Bye America” trade has a habit of returning when markets stop debating whether the US is still the safest house on the block and start debating the price of living in it. Over the past week, that debate has shown up in the dollar. A weaker dollar is rarely a story by itself, but it often arrives with a familiar set of consequences: global portfolios reassess how much US exposure they want, hedges get recalculated, and risk budgets get rewritten. Bitcoin has been catching some of that wind, but the move only makes sense once you look past the simple chart logic and into the mechanisms that FX moves into crypto. Bitcoin doesn't trade the dollar directly. It trades the conditions created by whatever is moving the dollar, especially real yields, hedging costs, and the way risk is rationed across portfolios. When those inputs line up, Bitcoin can behave like a macro alternative.
