High-return and high-risk investments are not suitable for ordinary investors, and are often accompanied by huge uncertainty and potential losses, which are likely to lead to no return. It is not recommended to make related attempts. For example： -**Futures investment**: With a certain commodity or financial asset as the target, investors can buy and sell futures contracts by predicting price movements. The futures market is highly leveraged, and investors only need to pay a certain percentage of the margin to control the value of the contract several times the margin. This high leverage characteristic allows investors to make huge gains when price fluctuations are favorable, but once the market moves contrary to expectations, it will cause huge losses or even burst positions. -**Foreign exchange margin trading**: Amplify investors' trading funds through leverage, and take advantage of exchange rate fluctuations to buy and sell for profit. Since exchange rate changes are affected by many complex factors, including politics, economy, and geopolitics, fluctuations are more frequent and severe, and investors may suffer serious losses if they make a slight error in judgment. -**Investing in start-ups**: Many start-ups face huge challenges in the development process and have a high failure rate. If the invested start-ups can be successfully listed or acquired at a high price, investors may get rich returns, but most start-ups may not achieve the expected development goals, resulting in no return on investment. Investment should be based on adequate understanding, risk tolerance assessment, and reasonable financial planning. Before making any investment, it is recommended that you fully learn relevant knowledge and consult a professional financial adviser.
