In the current investment environment, returning to the US stock market or the A-share market may be a more prudent choice for ordinary investors. Although A-shares are often criticized, if one can persist in long-term investments in rigorously selected ETF funds, the safety of investors' funds is relatively guaranteed due to the listing companies' review mechanisms and the strict selection criteria of ETFs. If investors can maintain patience and extend the investment horizon, they are likely to achieve steady growth of assets through the effect of 'compound interest'.

In contrast, the cryptocurrency market currently exhibits the phenomenon of arbitrary token issuance, excessively pursuing 'traffic' while neglecting 'quality', which makes the 'compound interest principle' difficult to apply in the crypto space. Although some criticize the strict listing and delisting review mechanisms of the stock market, in the long run, these mechanisms are beneficial to the entire industry and ordinary investors. As long as investors possess a certain level of patience and courage, stock market investments are likely to yield returns in the long term.

Unfortunately, the cryptocurrency market currently lacks the potential of a high-quality market. As Vitalik Buterin stated, the crypto space resembles building a 'large casino'. In such an environment, the 'compound interest principle' does not apply, and the outcome for ordinary investors participating in it is self-evident. Therefore, for the average person, the stock market may be a more suitable choice.
