Currently, market fluctuations are frequent, and the risks of single on-chain transactions are becoming harder to control. For long-term asset allocation and diversification of investment risks, focusing on long-term value assets like U.S. and Hong Kong stocks is a more reliable choice. However, traditional cross-border investments in U.S. and Hong Kong stocks have very high barriers—complicated account opening processes, currency exchange restrictions, and strict review procedures. Going through these steps not only consumes a lot of time and effort but also makes it easy to miss out on quality investment opportunities.
