AFAIK, it will not always help you do predict the price. In my opinion FA is better than TA consider about the latest news about blackrock is seeing crypto as an opportunity for them all to get the more market and money.
Predictions and speculations are uncertain so it can help you or it won't if your analysis wasn't so close to what's happening. What's FA? financial analysis? I don't mind what's better with that because sometimes TA does really work for me and it helps me to know if its a good time to buy. I don't usually sell but when I do, I never regret it because I'm more of a long term holder and investor to crypto. Blackrock did helped the market after announcing their interest.
