Technical and Fundamental analysis exist because they have a huge function when it comes to trading. Some just use TA, well, they are still profiting. That is why it is still an option for us traders which one to use but I suggest to consider them both upon trading as this would help you to have better results. But we have to remember that trading is not just all about TA and FA, in order to earn profit from trading, it should also be accompanied by effective strategies and hard work. In this way, your chances are pretty high.
