For most people, our biggest obsession is being confused by the fog of eyes, many people will feel that BTC will fall to 40,000 USD before Bitcoin rebounds to its current position. However, when BTC rebounded, these people began to think that it would rise to $100,000. All because we are distracted by the hustle and bustle before us. In fact, except for the price rebound, the market has not changed at all. We will even face a greater challenge, that is, this rebound is based on emotion. When the emotion ebbs, will the market proceed on a larger scale? This is what we need to observe, and we need to establish our own system to respond to changes in market trends.
