Many people’s positions become heavier, and their IQ drops accordingly.

This is an iron law.
When you’re trading with 100 U, your thinking is clear, decisive, and rational.
When you’re trading with 100,000 U, you become anxious, indecisive, and emotional, like a panicked rookie.
It’s not because you’ve become dumber; it’s because the position size is too large, and your survival instinct takes over your brain.
The first reaction of survival instinct is: Don’t move, danger.
So, reduce your position to a level where you can think rationally.
This is an experience shared in the cryptocurrency trading field, with the core idea that position management directly affects the rationality of trading decisions:
1. Strong correlation between position size and mindset: Small positions allow traders to maintain clarity and make decisive decisions; large positions trigger survival instincts, causing anxiety and hesitation, which distort decision-making.
2. The fundamental reason: It’s not a decline in intelligence, but the risk pressure from large positions that overwhelms rational analysis with emotions and instincts.
3. Actionable advice: Adjust your position to a level where you can think calmly and rationally, avoiding fear and greed from dominating your trading behavior.
This view is widely accepted in trading circles (stocks, cryptocurrencies, etc.), and fundamentally reflects the core principle of risk management:
• Over-leverage amplifies emotional fluctuations and is a common cause of trading losses.
