On a certain leading exchange's DeFi platform, you'll see that the annual interest rates for liquidity mining vary dramatically—from as low as 2% to as high as 800%. Behind this disparity, there's a key point that must be understood: these interest rates are not uniformly set by the platform but are determined by your ability to judge price movement trends. In other words, the more accurate your market predictions, the better the chosen liquidity range, and the higher your final returns. So how can you develop the optimal liquidity strategy? The answer lies in understanding the core logic of CLMM— in a concentrated liquidity model, you need to set your position based on the expected price fluctuation range. Only when the price moves within your selected range can your liquidity generate fee income. Mastering this methodology makes DeFi liquidity mining no longer mysterious.
