To be completely honest, the biggest fear when trading contracts has never been losses - it's the account dropping to zero.

Especially for friends with less than 10,000 U, they often end up going all in and then it's Game Over. I've seen too many new players who, with a few thousand U as starting capital, spend all night studying the charts, looking for experts to follow, and jumping in whenever there's a hot trend. And what happens? Three days of excitement, five days of an empty account, and ten days of disappearing without a trace. It seems like they're desperately trying to make a move, but in reality, they're just providing warmth to the seasoned players in the market.

I have also paid tuition myself. At that time, I had 20,000 U and wanted to double it quickly. I impulsively bought in during the price surge and panicked and added to my position during the decline. After a series of operations as fierce as a tiger, my account balance dropped to zero.

This lesson has made me completely awake, and I have established three iron rules afterwards. In 4 months, the account has steadily grown to 100,000 U, with zero liquidation records during this period.

**First Iron Rule: Position limit 50%.**
No matter how good the opportunity is, you can't bet all your capital. The market is never short of opportunities; what it lacks are those who still have bullets when the opportunity arises. Keep your ammunition ample, gradually increase your position when your judgment is correct, and retreat immediately if you make a mistake. Never stubbornly hold on.

**Second Iron Rule: Profit taking and loss cutting must be executed.**
The most common mistakes for beginners: holding on desperately when in loss, expecting a reversal, and being greedy when in profit, wanting to take more, ultimately leading to either liquidation or giving back all profits. Set rules in advance and strictly adhere to them; this is not being timid, but rather a fundamental quality of a professional trader.

**Third Iron Rule: If you don't understand it, don't touch it.**
Community calls, influencer recommendations, and the "soaring god coin" in short videos are nine times out of ten traps. Blindly entering without even understanding the project's fundamentals means you're not buying an opportunity, but rather a risk. It’s better to miss out a hundred times than to step into a pit once.

Stay calm when the market arrives, and be patient during market fluctuations. Protect your principal of 10,000 U, as it is the only way to have a chance to reach 100,000 U; adhere to trading discipline, and the market will reward you.

Many people can make quick money in the crypto world, but very few can survive steadily. If you want to survive in this market for the long term, first learn to protect your principal, then consider getting rich quickly—market conditions are always present, and opportunities arise at any time, provided that your account is still alive.

These three iron rules are the core logic for evolving from a retail investor to a stable profit maker. It's not that your actions are too slow, but rather that you haven't found the right direction. Have you ever been educated by the market due to following the crowd or greed? Finding the right rhythm is essential to breaking the cycle of losses.
