I won't completely say Bitcoin is unpredictable. Otherwise, what's the place of Technical analysis and fundamentals. But I agree with you 100% that it's important to know what to do when the price falls and when the price rises. Infact, the rise and fall of Bitcoin price is what excites traders. Others are exploring trading competitions like the Bitget Builders harvest time trading battle I found users discussing in one of the forums. It's that season where traders benefits the most from the price volatility
Price ups and downs in the market are indeed something that every trader loves because they do profit from it and it certainly happens very often in Bitcoin so predictions based on technical and fundamental analysis will always be there for Bitcoin although complete accuracy is always harder to find. However, it should still be considered normal because there are many people who are able to profit from these opportunities in the market because traders also often see certain moments and use them to gain more profits.
