All I know that there are profitable traders that only uses fundamental analysis and there are traders who use only technical analysis. So if we combine these two would definitely increase the rate of winning. In trading, the more confluence the higher the probability of winning the trade. But before you use in your actual trade, backtesting is a must. And remember, without risk management will just result to liquidation. So you must have a trading plan and stick to it.
Indeed! Fundamental analysis is good to use to see how would the project or coins perform since it deals with the foundation of the projects, the plans and the people behind it, while Technical analysis gives us the knowledge of when to enter and exit the market since these deals more on the previous and recent trend of the projects market price and its signal for the upcoming trend through some mathematical calculation.
The combination of these two may supplement each other weaknesses and possibly synergize the pros.
