According to CoinMeta, the comments from JD Vance have reignited debates about the dominance of the US dollar and the contradictions associated with Triffin. He pointed out that the global demand for the US dollar brings obvious advantages, including cheaper imports and easier government borrowing, but it may also lead to an appreciation of the dollar, thereby weakening the competitiveness of American exports. The views of Vance are in conflict with those of Triffin, which describes the tensions that arise when a country's currency also serves as the primary global reserve asset. Although Bitcoin is considered a neutral reserve asset, its volatility, storage risks, and limited adoption by central banks remain major obstacles.
