Nothing works 100% of the time, but technical analysis can create a decent gauge for where the markets are going and the possible inflection points along the way.
Everything in crypto feild is just an speculation no one knows what will be the future of this crypto currency it is tge same on trading. Analysis is just like. An speculation because we all know that this trading feild is also unstable if we trade coin we will depend on its volume and price before we do trading. So then I believe that trading analysis is just like an speculation, and maybe it has just having a great basis.
