Why do you always act as an "ATM" in the cryptocurrency market?

I've seen too many people: chasing highs during a bull market, panicking and cutting losses during a bear market, going all-in during sideways trading out of boredom. They learn a bunch of technical analysis but still end up losing to their emotions. Actually, in trading, managing your mindset is much more important than watching candlestick charts.

Based on my own pitfalls, here are a few strict rules:
**Rule 1: Invest with money that "won't affect your sleep" if lost**
What is idle money? It’s the money that, even if it goes to zero, won’t cause you insomnia, won’t affect your rent or utilities, and won’t cause arguments with your family. Once you use your living expenses or emergency funds, even a 20% drop can make you panic—any decision made at this point is basically wrong. The amount of capital determines your psychological resilience; don’t overestimate yourself.

**Rule 2: Stick to your plan and don’t fight the market**
The market won’t go up just because you’re anxious, nor will it stop falling just because you’re unwilling to accept it. Sell when it reaches your target? Yes. Exit when it breaks your stop-loss? Absolutely. It’s that simple and straightforward. The biggest problem for many is: hoping for more after a rise, thinking it will rebound after a fall—this kind of luck-based mentality is the root cause of retail investors losing money.

**Rule 3: Accept the reality of "not being able to make all the money"**
Let go of missed gains; don’t think about revenge trading to recover your principal. Trading is a game of probabilities, not a gamble with your life. Earning 30% less today is not shameful; as long as your principal remains intact, there’s a chance tomorrow. Those who try to catch every wave often end up missing the last one.

In short, surviving in this market is the prerequisite for making money. When your mindset collapses, even the most precise entry points won’t save you; when your mindset is stable, even if you’re slow, you won’t miss out on the long-term gains.
