The spot grid is a powerful tool for capturing profits in fluctuating markets. Although it isn't omnipotent—for instance, its feature of only allowing long positions can make it easy to become trapped in a one-sided downtrend—overall, the benefits outweigh the drawbacks. There are no perfect tools in this world; every tool has its place to maximize its value. It's only through continuous learning, understanding the tool itself, familiarizing oneself with the market, and recognizing personal risk preferences that we can find the most suitable money-making methods for the current market conditions.
