The movement of stablecoins often serves as a barometer of market sentiment. Once USDT or USDC starts flowing into exchanges, mainstream coins like a leading Layer1 token tend to follow suit. This is not a coincidence but a true reflection of market psychology. During FOMO seasons, this linkage effect is amplified tenfold. Investors immediately deploy stablecoins, fearing to miss the next rally. In simple terms, by observing the flow of stablecoins, one can anticipate the direction of large funds in advance. Straightforward but often very effective.
