US December economic data will become a key indicator for the recent cryptocurrency market. If non-farm payrolls, the unemployment rate, and wage growth outperform expectations, it will reinforce the Federal Reserve's stance on maintaining high interest rates, increasing the pressure for the US dollar to appreciate. This would put downward pressure on cryptocurrencies like BTC and ETH, making the overall market more vulnerable. Conversely, if the data shows weakness and expectations for rate cuts rise, a weak dollar environment could provide a rebound momentum for cryptocurrencies.

In addition to employment data, several other variables are worth paying attention to. Trump’s tariff decisions, energy policy directions, as well as economic indicators like the Michigan Consumer Sentiment Index and inflation expectations, will indirectly influence the performance of crypto assets by changing market risk appetite. If tariff measures are ultimately approved, rising trade uncertainty may trigger safe-haven capital inflows, which could be positive for Bitcoin in the short term. Overall, it is important to closely monitor the trends of these macro factors.
