I've just realized that in crypto, people often talk about the bull and bear sides. These two concepts are really important because they reflect two completely opposite market trends.

The bull side (Bull market) is when prices go up, investor sentiment is optimistic, and everyone is eager to buy. The image of a bull with horns pointing upward is used as an analogy for this upward price trend. Conversely, the bear side (Bear market) represents a period of falling prices, pessimistic market sentiment, and investors are fearful and want to sell off.

In fact, the U.S. Securities and Exchange Commission (SEC) also clearly defines these terms. The bull side is a period of higher prices and strong market confidence. The bear side, on the other hand, involves falling prices and negative sentiment.

Looking at BTC and ETH, you can see they constantly fluctuate between these two sides. Sometimes the bulls dominate, sometimes the bears regain control. The important thing is to understand which phase you're in so you can adjust your trading strategy accordingly.

The great thing is that when you clearly understand the difference between the bull and bear sides, you'll be more confident in making decisions. The market isn't always favorable, but understanding market psychology will help you avoid costly mistakes.
