History cannot repeat itself, but it is always remarkably similar. Looking back at the bull markets of 2017 and 2021, each bull-bear cycle coincided with the halving of Bitcoin. According to this pattern, 2025 will be a crazy bull market, and 2026 will enter a bear market. But will ETFs change the cycle, bringing the bull market earlier? Currently, we have not seen this. Only when Ethereum breaks through its historical high of 4800 and Bitcoin stabilizes at 70,000 can we confirm that the great bull market has begun. Once the great bull market is confirmed, please remember not to switch positions. 1. Why not switch positions based on market conditions in real-time? One reason is that most people's operations really cannot keep up; do not doubt this. Another reason is that for beginners, as long as they choose the right asset, not switching positions is already great wisdom. 2. Previously, when a certain coin was stagnating, some people began to feel anxious, saying that they saw everyone else rising, so why wasn’t it rising?
