Just recommend low-cost funds. If you invest in 300 yuan/month and each fund has 1 yuan, then you have 300 shares. If you invest in 2 yuan, then you have 150 shares. Of course, the premise is to see what kind of fund you choose. If it is a stock fund, it mainly depends on whether the stock he holds has room for development in the future, and also depends on the speculative level of the fund manager.
