I will not fully believe the opinions of those analysts, but I will use these analyses as one of the factors in my reference to market trends. In the end, I will still rely on my own judgment!
Don't depend to anyone just use their analysis as your guide but never rely on that one alone. Its good that you know how to read charts on your own and you can prove that they are wrong or they just really want to hype you on that specific coin. Chart analysis is very reliable, learn how to done it well.
I also do not believe in these charts because these charts based on predictions and in my point of view predictions about bitcoin price is almost 100% wrong. We can observe the previous years predictions about 2018 and saw the price in this year. After that I dint believe in any prediction. I analyze the market by myself and take decision about my holdings.
