in doing short-term trading, I think we are more inclined to use technical analysis than fundamental analysis, because we analyze the market every day. so it is not possible to use related fundamental analysis for long term. therefore every trader must be able to analyze chartists to find support and resistance to place transactions. and we certainly have to follow market movements more often. or we can place targets and stop losses and we can leave them.
Different types of strategy can be done once you are already familiar with how the market moves.
It's always depends from how you understand the situation and how you adjust with every market movements, same with other
trading industry, there are stiuation where you can buy when fear is dominating then sell when everyone are thinking that it
will pump for more, TA will give you hint and it's very useful if you know how to play it well.
The cryptocurrency market moves in 3 ways. And they are; Upward, Stable, and Downward. Once we know all these movements, we can also create 3 kinds of strategies for it. Crypto trading doesn't have a big difference from other trading markets. If there is one major difference that will only be volatility in crypto which are very high.
We are free to apply some strategies we have on other trading markets. The one that you are telling there which is to buy when others are fearful are I think mainly used for investing and not really for trading. The crypto trading is unpredictable but doing a technical analysis can be a big help to us to have a better success rate.
