Good thing that you decided to comeback. Upon reading your post, I guess you were an investor before and you are trying to engage yourself in trading at this moment. I am no expert in this industry but I would try to address each of your concern and share my idea about each of it.
First, do I need to study different technical analysis? Will it be helpful once I'm into trading cryptocurrency?
Technical analysis is an important thing to know about when you are about to move in trading along with fundamental analysis. Technical analysis is a combination of both examining and predicting the behavior of a market in order to come up with a "market pattern", which in this case, a trader would follow such as when and what to trade. Fundamental analysis on the other hand is seeking for the 'core' idea in the market such as what coins have a low market value, and what are the coins which are more expensive. These analyses would be a good determinant of a good trade.
Second, do you know some famous crypto fanatics whose giving some good tips about crypto trading which I can follow and learn from?
I cannot give specific names to who are the good ones to give advice on what to do in trading. But there is a trading discussion section in this forum wherein you may further read about this matter, which I think would be better than to seek or based to an individual, about what to do and what not, because there is an interaction, morr opinions, the more you can come up with an idea.
Lastly, what do you think are the good coins now to look forward to. I can see on the chart that there are lots of new coins in the top compared to what I knew way back few years ago.
It is hard to tell at this moment. We are currently in a situation wherein things could happen in a sudden. I would advise further observation until a "pattern" is already visible to which coins would be good, because in my opinion, determining at this point the good coins, is like jumping into conclusions.
I hope these answers will somewhat help you.
