On Monday morning, the crypto market responded with a decline. Bitcoin experienced a maximum drop of 3.79% within an hour, and many smaller coins retreated rapidly, with continuous plunges. Simultaneously, other assets also reacted—gold and silver prices strengthened, while stock index futures fell by 1%.

The trigger for this wave of market movement points to the policy developments over the weekend. After Trump issued tariff threats regarding Denmark's autonomous territory Greenland, multiple EU countries quickly activated response plans, considering retaliatory measures against related goods. The uncertainty in macroeconomic policies has always been prone to triggering rapid adjustments in risk assets. As a sector highly sensitive to policy changes, the crypto market's reaction is often more direct.

From a market structure perspective, this is not just Bitcoin's solo performance—altcoins with deeper declines indicate a clear weakening of risk sentiment, showing signs of capital flowing into safe-haven assets. In the short term, macroeconomic changes will continue to be the dominant factor, and further attention should be paid to new developments in US-European trade negotiations.
