Is this drop in SOL a precursor to a bear market?
In fact, a correction in a bull market is not scary. The main reasons for SOL not surging are that there are too many trapped positions above, leading to selling pressure whenever there is a rise, severely suppressing the price; secondly, most funds are flowing towards ETH, so there isn't much upward movement.
Once the funds in ETH are saturated, they will definitely flow towards promising targets like SOL. By then, if the trapped positions are largely digested and funds come in, it will be hard for SOL not to rise. For now, hold steady and don't panic sell; just wait for the rotation!
