The first day of December, the 31st day of the compound interest of 100 dollars, today’s profit is 150 dollars, 2.78% yield. Today is extremely difficult to do. The fluctuations and patterns are not in line with my trading logic. After being tripped by ustc, This month we are still mainly accumulating principal, so we will not expand our positions any more. The rate of return should not rise as sharply as last month, and we will still focus on stability.
