We should use both in market conditions like these. Mastering technical analysis without fundamental analysis is futile, and vice versa. But if you ask me which I prefer, I prefer fundamental analysis. It will make us confident in our choices and the projects we invest in. This is where I prioritize fundamental analysis.
Fundamental analysis is good if you don't want to spend much time with the technical but fundamental analysis does not always guarantee profits. You have to be really fast when you are dealing with fundamental analysis as you might have heard, buy the rumour, sell the news. You can only make profits if you were able to catch the rumour and validate the sources. Only then you can start filling your bags and wait for the actual news to roll out. Once it does, all you have to do is keep adjusting take-profits and relax.
But most of the times, these rumours would be faked just to trap innocent people who still want to buy the rumour and sell the news but does not have good market research capabilities. These people trust these rumours and start pouring their money. They hardly get any profits this way so OP, make sure you don’t turn into one of these people.
