U.S. President Donald Trump has issued an executive order to establish a national Bitcoin reserve while simultaneously banning Central Bank Digital Currencies (CBDCs). This unexpected policy shift has led to significant volatility in the cryptocurrency market, with both Bitcoin and Ethereum experiencing sharp price fluctuations as investors react to the new regulatory landscape. Trump's decision, aimed at safeguarding financial privacy and national sovereignty, marks a dramatic change in U.S. digital asset policy. The prohibition of CBDCs indicates a strategic move towards supporting private digital currencies, which could have profound implications for institutional investment strategies. Historically, similar regulatory announcements have caused initial market declines, followed by eventual stabilization.
