For long-term investment, it is clear that fundamental analysis is the main analysis that must come first... it is very basic, in fact some people might choose to use fundamental analysis alone with high confidence as their long-term investment capital... in the middle of the road, maybe they will find some price movements are sad, but the temporary wounds will heal and at some point their confidence will be greater to hold longer.
It's different if you want to look for short-term profits... the most important thing is technical analysis... even though market manipulation still often occurs in the cryptocurrency world, there is no other way than technical analysis for daily traders. Relying on the news can be an alternative for making decisions, but make sure you are not too late in getting the latest news.
