There is no such technology invented in the world so far that we can know in advance what we do will be profit or loss. If there was such a technology then no one would be harmed in business and there would be 100% successful businessmen in the world. Then maybe there would be no word of poor in the world, everyone would be rich. First of all, no technology has ever been able to predict anything in the past and will never be able to in the future.
All humans are unable to see the future, so everyone still has to continue working to make their future bright. Because basically everyone doesn't know what will happen in the future, even though everyone can reflect on the past to improve the way they work in order to get a better future and that is naturally the case.
I agree with you that it is not possible for any human being to predict the exact future. But only a little can be inferred based on past events and behavior. That is through by technical analysis. And someone with long experience can often predict the potential and thereby make good profit from crypto. So technical analysis cannot be untrusted completely
After all, everyone can see business people who are still working and running their business because they themselves don't know when their business will progress even though they continue to try to target the number of new customers every year. So regarding the future, we can only make the best of it from now on because good results only exist through good efforts from each of us, not from fortune tellers or other people.
Of course, to be successful at something, you have to stick with it for a long time. Because success never comes fast in any field. So in technical analysis also an analyst spends a long time and after hard efforts is able to make a correct analysis which fetches him a good profit at that time. That's the truth and that's what happens
