When I first entered the crypto world, I was no different from most people—spending over 12 hours a day in front of the screen, with candlestick charts covering the table, and all kinds of indicators dazzling my eyes. MACD, Bollinger Bands, RSI taking turns, stop-loss orders set so tightly you could hardly breathe. And the result? After all the fuss, my account shrank to a pitiful level.

After that blow, I finally understood a principle: the most overconfident traders in the crypto space are those "technical enthusiasts." Those seemingly sophisticated indicator strategies are fundamentally flawed in the face of market sentiment. When you see unrealized losses making you nervous, or FOMO pushing you to chase after gains, all those precise strategies become worthless paper.

Later, I changed my approach and started to feel more comfortable. My core logic is actually very simple—do only subtraction, not addition.

**About Choosing Coins**

Now I only deal with two: Bitcoin and Ethereum. Those small coins claiming to multiply tenfold in a day? I ignore them completely. It sounds conservative, right? But the truth is this—mainstream coins may not rise as wildly as altcoins, but they will never let you wake up to find your investment wiped out. They are backed by real consensus and ecological support. Even if they crash, they can recover. Small coins, on the other hand, might truly be gone forever.

**About Trading**

I no longer focus on every single daily candlestick; instead, I only look at one thing: weekly trend. As long as the weekly trend is upward, no matter how fierce the daily fluctuations, I remain steady. For example, in June this year, after Bitcoin broke through a key resistance level, I added to my position (controlling it at 30% of my total assets). Although there was a 20% pullback, I refused to cut my position. As a result, by July, my profits doubled.

A special note: true "trend" is not guessed; it is formed by the market’s actual movement. Many people always think about perfectly bottom-fishing or perfectly top-selling—that’s wishful thinking. But if you understand the market’s rhythm and follow the trend, you are already ahead of most traders.

**About Position Sizing**

This is the most overlooked but most critical point. My principle is never to use all my bullets at once. I keep 30% of my active capital to seize opportunities, while the rest is diversified or just sitting in the account. What’s the benefit? Peace of mind. You won’t be forced to cut your position during a correction, nor will short-term losses throw you into chaos. In the long run, this "conservative" position management actually makes my returns more stable.

My current understanding is: the profit logic in crypto is really about simplifying complexity. The more you stare at the screen, the easier you are to be driven by emotions. Conversely, the "dumb" methods—only choosing mainstream coins, riding the trend rather than fighting it, controlling your position size—are the real moat.
