The euphoria of the last few weeks has abruptly transformed into a debacle for crypto investors. In just 24 hours, over a billion dollars worth of positions were liquidated, taking with them the hopes of a prolonged market rebound. At the heart of this shock is a new wave of economic uncertainties, amplified by the United States' decision to impose 25% tariffs on Canada and Mexico. This announcement triggered a sudden drop in traditional markets, as well as a collapse of Bitcoin and major cryptocurrencies.
