in simple, my question is , does technical analysis work every time and can we predict every move using technical analysis or times when we should not predict price using technical analysis
Obviously, technical analysis will be one of your reference in making your future strategy. Just keep in mind that it won't guarantee you to work every time so don't rely mainly on it.
And yes, you can predict
"some possibilities" by using technical analysis. However, here in crypto, no doubts that technical analysis does not always work most of the times due to the fact that crypto is heavily volatile. Even on a strong bullish run, you can always expect that something will spoil the momentum along the way even how properly backed-up a certain analysis is.
So what to do now? While looking for some technical analysis, also consider other factors such as current events, news, monitoring daily volume and even your
"own instinct".
being knowledgeable with TA is the basic foundation that you can have in trading. however, this doesnt work mostly in crypto especially the newly created ones. check for the background of the coin, the activities surrounding it, the hype they are creating and many other things that you can only assess by following them.
without prior knowledge before trading them in exchanges would be a suicidal move as you might be trapped in a pump and dump scheme coin or the soon-to-be-dying coin and be left a bag holder of worthless coins!
