Five years ago, on that early morning, I was awakened by my phone's frantic vibrations.

I opened the screen, and all I saw were platform notifications about liquidations. Three hours, 6 million turned into zero. I stared at those numbers in a daze, my mind completely blank—it's not that I couldn't believe it, I genuinely hadn't processed it. Later, my friend said I looked like a walking corpse those days, with a dazed and devastated expression on my face every time I saw someone.

At that point, I realized that this market has never been a game of overnight wealth, but a battlefield of real guns and real battles. If you don't understand the rules, the market will teach you how to behave in the cruelest ways.

I borrowed 120,000 by scraping together funds, then began to review those failed trades. Watching charts, analyzing strategies, studying various technical indicators, staying up countless nights, I finally developed my own trading system. Once my win rate stabilized at 90%, I turned that 120,000 into 70 million in 90 days. It might sound like bragging when I say this, but I still keep screenshots of every single trade.

Today, I want to talk about the most basic yet most overlooked topic—why do prices go up and down?

The answer is actually very simple: when more people buy than sell, the price goes up; conversely, it goes down. But knowing this and understanding it are two different things. Most people stare at candlestick charts but cannot sense the forces at play behind the scenes.

Taking Bitcoin as an example, it is still primarily driven by spot price. Therefore, the strength of the bears mainly comes from large players selling off or longs closing positions. Of course, for easier understanding, we can view it as a market where bulls and bears are engaging in a full contest—so after learning this, you'll be able to understand the charts of other cryptocurrencies as well.

In the next article, I will analyze several real cases to teach you how to read the actions of the big players from candlestick patterns.
