It's true that what you say is that there are no 100% accurate predictions, it's just that perhaps by predicting them we can understand a little of the developments that are occurring.
-cut-Same in the case here, but the technical analysis of the people are so strong the in the trading not all but some of the traders who have studies the coins and they have even all the information about the graphs of the coins. But still the may fail at some points due to the market up and down. So I didn't fully believed in these things like following them on different occasions.
Yes I agree with that, as I said no prediction is 100% accurate.
In fact, predictions always involve uncertainty (speculation), but having experience and knowledge can help us manage risk. Although technical analysis can be powerful, market fluctuations remain a factor that is difficult to fully predict.
Actually, all of us here in the forum are all speculations; now it's up to us if we agree or support what they say. That's why, if we become sensitive, we will know which useful things others are saying and which are meaningless.
The performance of technical analysis requires that we have an understanding of the use of tool indicators so that we can determine what and where the direction of the coin we are trading is to obtain income. It cannot be said that you know how to use technical analysis if you do not know how to use indicator tools.
