Buying a fund can make money, but it may also lose money. This depends on whether the quality of the fund you choose is good, and whether the time when you buy the fund and the time when you sell the fund are accurate.
So buying a fund is risky, but compared with stocks and futures, the risk is relatively small.
If you have no investment experience, you can choose to invest in the fund, and invest less money every month, which will not affect your life. You don't need to consider the time of entering the bank, and you can redeem it if the income reaches the expected goal. Moreover, the fixed investment of the fund is compound interest, and timely financial management is also saving money.
