The US has announced it will reduce tariffs with China, along with the possibility that a meeting between Trump and Xi Jinping in May is accurate and will proceed smoothly, which is indeed very positive news for the global financial market, including the crypto market.

For BTC, the reason for the strong increase may come from:

1. Optimistic market sentiment: Any signs that US-China trade tensions are easing lead to capital flowing into risk assets like Bitcoin.

2. Expectations of FED easing: A more stable international relationship could boost monetary policy to support growth.

3. Investors anticipating news waves: The crypto market is very sensitive to major news, so speculative capital also contributes to driving prices.
