Staring at the wildly fluctuating candlesticks on the screen, I finally figured out a principle: in this market, it's not about how clever your brain is, but who can stay calm.

I still remember when I first entered the crypto world, hearing people talk about "support and resistance" was like listening to a heavenly book. At that time, I naively thought, isn't it just drawing two lines? The first time I tried to buy at the so-called "support level," the price dropped like a cut kite, and I lost an entire two months' salary.

Later, someone asked me how I analyze the lines and when is the safest time to enter. I smiled—not mockingly, but because I remembered my own past struggles. Today, I share the experience gained from blood and tears, hoping everyone can avoid a few pitfalls.

**Lessons Learned from Losses**

When I first started trading crypto, I was no different from most beginners—chasing rallies, panic selling, bottom fishing, adding positions and holding stubbornly—I've stepped into all the traps.

I used to believe in news sentiment, rushing in whenever there was a stir about a coin. I also chased hot trends, following whatever concept was popular. But what happened? When I entered, the market reversed, and I had not even realized my profits before they evaporated, sometimes even losing my principal.

The harshest lesson was in 2020, when I went all-in at a "steel support level," only for that support to be broken, and the price continued to halve. Because I used leverage, I was liquidated immediately, and my account was wiped out.

After that, I calmed down and started to reassess the market. I realized that support and resistance are not precise lines but zones. And they are not foolproof; they need to be combined with other indicators for comprehensive analysis.

**Practical Insights from Trading**

Through repeated trials and errors, I developed a method. Judging support and resistance cannot rely solely on price; volume and time cycles are also crucial. Support on a short-term cycle might be insignificant on a longer cycle. The effectiveness of support and resistance varies at different stages of the market. They may be useful early in a trend but can trap you in the late stages.

Most importantly, mindset. The market often hits you with a reality check. Whether you can withstand the pressure and accept losses is the fastest way to grow.
