In the field of Virtual Money trading, many people misunderstand 'rolling investment' and equate it with high-risk Margin Trading. However, the true rolling investment strategy is actually a relatively conservative approach, centered on gradually expanding the investment scale by utilizing the profits obtained, while strictly controlling risks.

The basic principle of this strategy is: investors only use a small portion of their initial capital for trading, for example, using only 10% as margin. In this way, even in the event of unfavorable market conditions, the maximum loss is limited to an acceptable range. As profits accumulate, investors can gradually increase their trading scale while still maintaining a low leverage level.

To ensure the effectiveness of this strategy, investors need to adhere to several key principles:

1. Strictly control the leverage ratio: Ideally, the leverage ratio should be kept below 3 times, with 1-2 times being safer. This can greatly reduce the risk of liquidation and leave ample room for consideration in investment decisions.

2. Set a reasonable stop-loss: It is usually recommended to set the stop-loss point at around 2%. This can effectively control the loss of a single trade and protect the overall capital safety.

3. Gradually increase the investment scale: As profits accumulate, the trading amount can be moderately increased, but the increase should be cautious to avoid taking on excessive risks due to overconfidence.

4. Be patient and disciplined: Successful rolling investments require time to accumulate. Investors should resist the impulse to significantly increase Margin Trading or positions in the short term.

5. Continuous Learning and Analysis: The market environment changes rapidly, and investors need to continually update their knowledge and analyze market trends to make more informed decisions.

It is important to emphasize that while this strategy can effectively control risk, the virtual money market itself is highly volatile. Investors should still act with caution and not invest funds beyond their capacity. At the same time, they should thoroughly study relevant laws and regulations to ensure that their trading activities are legal and compliant.

Overall, a low-risk rolling investment strategy offers small capital investors a relatively safe way to participate. Through strict capital management and risk control, investors have the opportunity to gradually accumulate wealth in this market filled with opportunities and challenges. However, this requires investors to possess sufficient patience, self-discipline, and learning ability to achieve success in long-term practice.
