Why did Bitcoin suddenly plunge?

Today I looked at several possible reasons that everyone said

1. An transferred 130,000 BTC internally

2. An An froze the crypto assets of Palestinian users

3. ARKB, the Bitcoin spot ETF, had an outflow of more than 100 million US dollars

4. September was after the market downturn

5. This BTC retracement came from the liquidation of long leverage and the decline in US dollar liquidity

Various opinions, there are many different opinions, the dealer does not need to give an absolute reason if he wants to smash the market
