Start with 300 yuan to build a contract, the key is not to be greedy. My approach boils down to these points:

**Initial Sprint (from 300U to 1100U)**

Divide into three stages, each starting with 100U, using 10x leverage, taking 7% profit to close, and cutting losses at 5%. This risk-reward ratio is 1.4:1, providing relatively stable single trades.

Stage 1: Turn 100U into 200U, take 70U profit and exit, with a maximum loss of 50U. If successful, continue; if not, with 200U remaining, rethink.

Stage 2: Operate from 200U to 400U, where emotions can run high. The goal remains 7% profit, 140U, with a stop loss at 100U. If it fails, set a floor at 100U and stop.

Stage 3: Push from 400U to 800U, following the same logic—take 280U profit and stop. If this stage also fails, cease high-leverage operations.

**Why limit to 3 attempts?** Because luck plays a big role. The probability of winning three times in a row isn't low, and continuing beyond that is pure gambling mentality. After completing this phase, if you reach 1100U, change your strategy.

**Stable Phase with Three-Layer Operations (starting from 1100U)**

Once reaching 1100U, you can't go all-in on one direction. My approach is to run three modules in parallel:

- **Ultra-short-term trading (allocate 300U)**—fast entries and exits on 15-minute charts, suitable for market oscillations to scalp profits.

- **Swing trading (allocate 500U)**—look for opportunities on 4-hour K-lines, a relatively stable cycle with higher tolerance for errors.

- **Major trend sniper (allocate 200U)**—bottom-fishing or topping out on weekly charts, rare opportunities that can signal big market moves.

- **Emergency fund (reserve 100U)**—for black swan events or extreme opportunities.

**Asset selection is crucial**

Stick to BTC and ETH, avoid altcoins. Altcoins have poor liquidity; a large order can cause a sharp drop, making risk uncontrollable. Major coins may not have as big swings, but at least you can survive and exit safely.

The core of this strategy is: quickly accumulate capital early on with high leverage, then immediately reduce risk once targets are hit, using time to generate returns. Only this way can you stay long-term in this market.
