I work in a bank. I have been buying Harvest 300. Of course, I am losing money now. In addition, I want to remind you that buying a fixed investment requires a long-term plan, and make it a habit and stick to it for a long time. As for the amount of fixed investment per month, it should be determined according to your economic income, which is generally 100 yuan. The lower limits of different funds in 200 yuan, 300 yuan and 500 yuan are also different. The lower limit of one base 50 and Jiashi 300, if I remember correctly, is 100 yuan.
