Technical analysis will help us to make some decent profit because we can easily guess the prices through the technical knowledge, but whereas through fundamental analysis some time our strategy will not work and I have experienced much time like this by failing.
They both have where they function well, like technical analysis now, I think this functions perfectly well for those that are trading in a daily basis, indirectly, it functions more for short term trade, and it is not so easy to go about it, it takes someone who have the knowledge of how to read those charts that will find it very easy to apply technical analysis to their trade anytime they need it.
Fundamental analyses is quite more useful when you are such a trader that trades in a long term, it is easy to follow news as strategies for long term investment. Majority of people holding their coin did so following the fundamentals that are happening around bitcoin in a particular time which they are sure will affect future. Like the bakkt that will release now, some people have already bought some coins ahead of it.
Fundamentals is the most used analysis indeed but not only for long term investment, I am as an active trader do the fundamentals analysis first and then look at the chart pattern as a technical one.
You can always use both fundamentals and technical analysis at the same time , why not ? It's not against anyone rules, not against anything.
I won't call my self as a hypocrite that the technical analysis is better , because yeah everyone know ... math and numbers is the most trusted thing in the world they don't lie , but media do a lot of lies.
