The weather has been freezing these past few days, and a gust of wind when you step outside feels like the Ice Age is arriving early. Opening the market chart, the crypto world is also experiencing a similar "winter."

Bitcoin has been quite interesting these days—just a few days ago, it was dreaming of spring, rallying a bit and releasing some hope, but within a few hours, it was knocked back to its original state. Honestly, it's like drinking hot coffee in the morning feels comfortable, but by the afternoon, your hands are still cold—very brutal. This wave of repeated fluctuations really tests people's mental resilience, and the quick switch between gains and losses catches many off guard. Such volatility may continue in the short term, so mental preparation is necessary.
