Many people tell me that they only have a few hundred dollars, and wonder if it's already too late to enter the crypto space. After all these years of market cycles, is there still any opportunity for small retail investors? To be honest, there are still opportunities. But you need to understand one thing—what's played in this market isn't luck, but a sense of rhythm and disciplined execution.

Today, I want to share a strategy that I have verified with real money. Starting from 100U, using a strict "three-layer advancement" approach to gradually grow the principal. This isn't a get-rich-quick story, but a practical summary of how to survive and thrive in the crypto world through discipline and patience.

**Stage One: The "Triple Doubling" Test with 100U**

The goal at this stage is simple: turn 100U into 1600U. It sounds easy, but most people never get here. The problem isn't technical; it's that they can't control their hands.

My trading rules are straightforward—strict:

— Only move 100U at a time, focusing on mainstream coins with hot topics and active trading volume. Never touch obscure small coins. In other words, accumulate wins with the lowest risk.

— Take profits at 20%, cut losses at 10%. This isn't advanced skill; it requires mental discipline. When the coin is rising, resist greed; when it's falling, resist softness.

— Never fully commit your position, never go all-in. Each trade is an independent probabilistic event. Don't carry over emotions from previous losses or gains. Only then can you survive longer.

The key word for this stage is discipline. Your real opponent isn't the market but the monkey called "greed" in your mind. If you can pass these three hurdles, you'll gain not just a principal of 1600U, but a lifelong trading logic.

**Stage Two: The "Three-Layer Strategy" After Reaching 1600U**

By this stage, you've developed a basic trading mindset. Now, it's about how to make your money grow more efficiently, rather than chasing trends blindly.

Layer One—Mainstream Coin Holdings (50%): Choose coins like BTC, ETH with larger market caps, holding for about a month. The volatility is smaller, but stability is the advantage—this is your account's ballast.

Layer Two—Hotspot Rotation (35%): Alternating between ecosystem coins and thematic coins. This year might be AI concepts hot, next year RWA (Real-World Assets) could take the stage. Follow the rhythm of hot topics, entering and exiting with discipline, keeping single-trade risk within 5%. The goal here is to increase returns, not to go all-in on one direction.

Layer Three—Small-Amount Experiments (15%): Reserve this portion for trial and error, learning new coins or trading strategies. Losses are limited, but you might discover the next ten-bagger.

**Stage Three: Mindset Management After Breaking 10,000U**

When the principal surpasses 10,000U, many people's mindset begins to change. They want to make 50% profit instantly, fearing to miss any opportunity. But the most dangerous thing at this point is impulsiveness.

My approach is the opposite— the larger the principal, the more you should reduce leverage. Take profits when due, without greed; cut losses immediately when needed. Sometimes, watching a coin rise and resisting the urge to chase is the highest form of operation.

Throughout this process, what is true leverage? It's not borrowing money to increase positions, but the compound effect of discipline. Small funds can win because they act quickly, make clear decisions, and carry light psychological burdens. As long as you stick to the rules, maintain your strategy, and control your emotions, you can grow steadily—everything is possible.
