Eight years ago, I entered this circle with ten thousand yuan, and now my account is steadily holding 38 million. This is not a legendary story, just time + discipline + countless mistakes and corrections. Today, I will share the pitfalls I've stepped on over the years and the truly effective strategies.

**First Ironclad Rule: Position Management Is a Life-Saver**
Never fully allocate your funds. Only use one-fifth of your capital each time; if you lose, it won't hurt badly, and if you gain, take profits immediately. Set a hard stop: a 10% loss per trade must be cut, no matter how tempting the market looks. Even if you lose five times in a row, you only lose at most 50% of your principal, but as long as you catch a trend, a few rounds of taking profits will recover it all.

**Second Insight: Follow the Trend, Don't Bottom-Fish**
When the price is falling, no one can predict the bottom; buying early is like burying yourself alive. What's the smart move? Wait for an upward trend to emerge, then buy on dips. Entering the market at this point is low risk and high probability, avoiding betting your life on the market.

**Third Point: Stay Away from Coins with Explosive Growth**
Coins that double or triple in a day look exciting but are actually dangerous. You think you can still rush in, but they’re already waiting for you to take over. Especially altcoins — once they pump, they crash; nine out of ten times you get caught.

**Technical Analysis I Only Trust One Indicator: MACD**
When DIF and DEA form a golden cross below zero axis, that’s my favorite buy signal. Once it crosses below zero on a death cross, immediately reduce your position and exit — securing profits is the real goal.

**A Deadly Mistake: Averaging Down**
Adding to a losing position is like throwing money into a pit; doing so when you're winning is the right way to roll the snowball.

**The Big Secret in Volume**
When the price breaks through a low point and volume suddenly surges, it’s usually a signal of the main force entering. Those who dare to follow at this moment often catch the entire main upward wave.

**Final Core Principle: Follow the Trend + Manage Risks**
When the daily chart, 30-day, 84-day, and 120-day moving averages turn upward, follow along; once the trend reverses, decisively exit. This isn’t about talent, but discipline.
