If my estimation is correct, the early morning decline this morning should be due to the potential geopolitical risk escalation signal released by the Middle East withdrawal operation, which triggered investors to reassess the market safety margin and inflation path, and thus began to reduce their holdings of risky assets. Both the US stock market and BTC have experienced simultaneous declines. There are more detailed explanations in today's homework, but it's also possible that I made a mistake in my estimation.
