The "Tariff Replacement for Federal Income Tax" policy proposed by the Trump administration aims to offset the income tax burden on low- and middle-income groups by increasing import tariffs. If implemented, this policy will have a profound impact on the structure of the U.S. economy, inflation levels, and the cryptocurrency market. In the early stages of the policy, the market may experience fluctuations due to uncertainty, but in the long run, if inflation persists and the regulatory framework improves, cryptocurrencies will benefit from anti-inflation demand and institutional capital inflows. Therefore, the medium-term outlook is bullish, but close attention must be paid to changes in Federal Reserve policy and the evolution of international trade dynamics.
