First, it's ok to have a good profit level, but only when you really know how much money he earns can you judge whether his profit level is sustainable. I am a professional stockholder myself, and I know the difficulty of raising a family by speculating in stocks, and the key is to have enough principal, otherwise it is a dream to make a living and seek development at the same time; Moreover, at the beginning, such things as futures should be able to withstand losses, and futures can do without losses. I have never seen it.

Second, two years is too short, and there will be contingency in it. Even if you make money in the past two years, it doesn't mean you can make money in the future.

Third, you have a deeper understanding of stocks and futures and ask more questions. For example, did the stock earn last year, how much did it earn, how much did it earn in futures, how much did it earn, and how much was the principal; What else are you going to do? And so on.
