I don't think that you can make sure profits even if you learn TA and FA. When I started my crypto journey I thought that trading would be a good idea if I learnt the necessary skills and that I could take it as a part-time job, but after reading to writers who are very knowledgeable and still very critical on this subject I believe that trading is too risky, and not only for beginners.
I will not be the one to take away your desire to learn and put into practice your knowledge on the subject, but I would take it more as a hobby than as an actual side-career.
Trading is more than acquiring knowledge, its technical and fundamental analysis, and even if you have those basic skills and strategies that work for others, still there is no guarantee that trading will be profitable on your part, most especially for a beginner like OP.
You know, trading is more complex than it seems. You are trying to win in such a speculative market, that’s why it’s really hard for us to gain sustainable profits. And if ever we have gained at first, that does not mean that there will be fixed outcome the next time we trade.
In fact, every trading opportunity comes along with challenges on how to end it up favoring on our side, because mostly, no matter how positive our trades look like, we still end up losing due to unpredictable and unfavorable market behavior.
