1, not all funds can't be sold, only closed-end funds can't be sold, and open-end funds can be sold whenever and how much.

2, the fund is a new way of financial management, the risk is greater than bank deposits, less than stocks. The fund is a long-term investment project. If you want to get higher returns in the short term, then the fund is not a good choice. But if you are patient, you can invest in the fund for a long time. Investment funds must use idle money that is not usually used, and don't invest too much at a time, and then increase investment when you know something about this fund.
