Generally speaking, when very bad things happen, most assets first experience a big dump, because the first things to become scarce are the most liquid items, namely cash. Most people do not hold a large amount of cash, so they need to quickly liquidate to make some preparations/adjustments to cope with an uncertain future.

However, once this short-term "cash panic" is over, it quickly moves into the next stage, as the environment becomes bad enough that people will refuse to hoard cash. More and more cash is released and then used to buy back those assets that hold more value in chaos, such as gold and BTC, to combat the rapid decline of cash's purchasing power against physical goods (which is known as hyperinflation).

So the sudden fall of BTC is just because there isn't enough circulating money in a short period of time; on the contrary, the continuous rise of BTC will be the main theme going forward.

Today is the best opportunity to get on the bus.
