How can we predict the market trends by observing the fluctuations in the USDC/USDT exchange rate?

Americans generally use USDC for deposits and withdrawals, but the mainstream trading pairs on exchanges are USDT. When the USDC/USDT exchange rate drops, it indicates that Americans are making deposits, using the deposited USDC to buy USDT, which causes the exchange rate to fall, and then using USDT to buy the dip in the spot market, leading to a rise in the overall market.

Conversely, when the USDC/USDT exchange rate rises, it indicates that Americans are starting to sell, then using the sold USDT to buy USDC for withdrawals, resulting in an increase in the USDC/USDT exchange rate and a decline in the overall market.

Recently, I saw a prominent figure mention this pattern. Today, as the overall market plummets, USDC unexpectedly rises, and looking at the exchange rate trend aligns with this pattern. There are also some interfering factors, such as the USDC/USDT exchange rate rising during Binance's launch pool.
