Fixed investment is ok, but it is not recommended. For example, just because the money fund gives a high return now does not mean that it will be high next month. I think those with lower income can vote according to the situation and see which one is stable and high. Of course, you don't have to jump around all the time, so you will spend time wandering around and vote when you see a big difference. You can't be too lazy to make money. In fact, you can download a software from your mobile phone, pick it up when you are bored and continue to observe it for a while. I think it's ok to turn around. The mobile phone is very convenient to operate.
