Buying a money fund means buying a fund in the form of coins, not stocks. Money funds are usually issued by major banks or fund companies to return investors at a fixed interest rate. Compared with other funds, money funds are less risky, and investors can buy and sell at any time without worrying about the risk of price fluctuations.

Buying a money fund is a relatively stable investment method, which allows investors to avoid some high-risk investments. Generally speaking, if you have spare money and don't want to put it in the bank, you can consider buying a money fund. Although its income is not as high as that of high-risk investment, it is basically guaranteed, and it is also higher than that of bank demand deposits.

Buying a money fund also needs to pay attention to some matters. First of all, we should pay attention to the scale and liquidity of the fund. Money funds with small amount of funds and poor liquidity have risks such as being unable to pay in time, so they should be purchased cautiously. Secondly, we should also pay attention to the management fee and sales service fee of the fund, so as to avoid being deducted too much fees and affecting the income. Finally, we should have a certain risk awareness, maintain a reasonable degree of investment dispersion, and don't put all our funds into the money fund.
