From entering the market at age 30 to now at 38, I have been navigating the crypto market for a full 8 years. During this time, I have experienced several complete cycles—crazy surges, sharp declines, platform shakeouts, I’ve seen all kinds of market conditions.

Honestly, I’ve made over 60 million yuan in this market not because of any super intuition or incredible luck. What supports my stable profits is, frankly, a very simple "343 Investment Strategy."

Taking Bitcoin as an example, suppose I have 120,000 yuan in available funds to invest.

**Stage 1: 30% Position to Start**

I would first invest 36,000 yuan, which is 30% of my total funds. Why not go all in at once? The main purpose isn’t to chase higher gains but to keep my mindset stable. Entering with a small position means I won’t panic regardless of market fluctuations, and the risk remains within my control. This way, I have room to respond to subsequent market changes.

**Stage 2: Gradually Add to 40%**

After establishing the initial position, the next step is to steadily increase my holdings. If the market rises? I don’t chase the top; I patiently wait for a pullback before adding more. If the market falls? I set clear rules—each time it drops 10%, I add another 10% of my position, gradually building up to 40%. What’s the benefit of this approach? No matter which way the market moves, by operating in batches, I can average down my cost, and a single misjudgment won’t cause a big loss.

**Stage 3: Final 30% to Close**

The last 30% of my position is key to profits. I would never blindly add to my position when the trend is unclear. Only when the market trend is fully stable do I top up this 30%. This makes the entire investment process clear—avoiding missing out on trend benefits while also preventing unnecessary risks from early heavy positions.

It sounds simple, but the core of this method is: risk control, diversification, and following the trend. This logic applies to Ethereum, Bitcoin, and other cryptocurrencies.
