Price goes up, it rises; price goes down, it falls—there's no surprise there. The question is, how do we know whether we're making a profit or a loss?

It's actually very simple—if you buy and it goes up, you make money; if you buy and it goes down, you lose money. That's it.

Since we can't know in advance whether we'll make money, what’s the point of watching these coins? There is a point. What we can do is keep observing. Open your phone, stare at the price movements with your eyes, see what it's doing, and understand your position. Many people want a crystal ball to predict the future, but prediction itself is a false proposition. Instead of trying to decipher an unpredictable future, it's better to clearly see the data in front of you—this is the reality of investing.
