In the cryptocurrency market, contract trading has become a widely popular investment method. This trading model, which originated from traditional financial markets, amplifies investors' capital through leverage, providing investors with opportunities for quick profits. However, high returns are often accompanied by high risks, so mastering a robust contract trading strategy is crucial.

First, choosing the right cryptocurrency is the foundation of successful trading. In a bull market, investors should focus on strong-performing cryptocurrencies, such as mainstream coins like Ethereum (ETH). Conversely, in a bear market, shorting relatively weak coins may be wiser.

Secondly, the choice of opening price is often more important than other factors. Due to the high volatility of the encryption market, most traders find it difficult to accurately grasp the best closing timing. Therefore, entering the market at a reasonable price can lay a good foundation for the entire trade.

Additionally, risk management is key to protecting funds. When a trade is profitable, it is recommended to take partial profits while setting the stop-loss point for the remaining position near the cost price. This strategy can both lock in some gains and effectively control potential losses.

Finally, the core of contract trading lies in accumulation. Through continuous small profits and the effect of compound interest, investors can gradually increase their capital pool. Once the trading starts to generate profits, measures should be taken to protect the gains obtained to avoid turning profits into losses due to market fluctuations.

Overall, while contract trading is full of opportunities, it also comes with significant risks. Investors need to operate cautiously, devise reasonable trading strategies, and always keep in mind the importance of risk management. Only then can one remain undefeated in this challenging market.
