Did you all sleep last night? Bitcoin dropped directly from 91000 to 85000, losing 6000 dollars just like that.

The group is once again spreading rumors about "a certain country's thirteen ministries jointly cracking down" and "a certain central bank governor suddenly resigning"—brothers, let's pause for a moment. These are all old tropes; they were confirmed as false news over the weekend, and yet they are still being spread?

**The real thunder is on the other side of the Pacific.**

This morning at 7 o'clock, the Bank of Japan suddenly announced an interest rate hike. You might be thinking: What does Japan's interest rate hike have to do with me? It matters a lot. For the past decade or so, Japan has been the cheapest source of funds in the world, with countless institutions borrowing yen at low interest rates and then investing in high-yield assets like US stocks and cryptocurrencies. Now that the faucet has suddenly been turned off, this money needs to be quickly pulled back to pay off debts, and assets with high volatility like Bitcoin are the first to be sold off.

Does the timeline match? It matches perfectly. One hour after the official announcement from Japan, the USD/JPY exchange rate fluctuated sharply, and then the cryptocurrency market began to crash.

**Don't just focus on the Federal Reserve in the future, remember two new indicators:**

• USD/JPY exchange rate — The yen appreciates, indicating capital inflow back to Japan, putting pressure on the coin market.
• Japan's 10-year government bond yield — when this thing rises, global assets will tremble.

There are two key dates coming up, it's advisable to set an alarm:

**December 10** — The Federal Reserve's interest rate meeting, whether to lower the interest rate or not may become a "shoe dropping".
**December 19** — Bank of Japan meeting, let's see if they will continue to tighten policy.

Today's wave is just an appetizer. The real eye of the storm is in Tokyo, and the crypto world is just an innocent bystander affected by it.

To put it bluntly: **90% of the time should be spent observing, not acting.** Buying on the dip and chasing on the rise is the standard posture for being liquidated. When liquidity tightens, hold cash and wait for the real opportunities to arise. Only when the tide goes out do you discover who isn’t wearing pants; this is that moment.
