If you grope for it yourself, the method is wrong, or there is no good enough way to protect the principal, you may not succeed for many years. Just like how many years you can play basketball, how many years you can play games.

If you have a person who can make money in futures, and learn the essence of this person well, and even find a way that suits you better, then this speed is still quite fast, and you may succeed in two or three years.

However, it is not easy to find someone who can make money in futures. It's not too difficult for this person to take and talk about the essence.

So it is not very meaningful to consider this time limit. The key is to look at your own situation. Most people can only find out for themselves, and most people will eventually quit because they can't do it.
