For better trading outcome combination of technical and fundamental analysis is the best. Whether you are trading for long term or for day trading you will need both technical and fundamental to confirm trading set up for entering the trade. I was working mostly with Technical analysis because it was telling me what is happening in the market currently but once there is any adverse news the whole system will fail and loss will come.
My early attempts at technical analysis didn't get me anywhere. It didn't really give good signals, and would change as the precious information changed. However this wasn't for crypto, but for forex. Crypto in general is a lot more explosive I think, and the news has a huge effect.
