I think it's natural for bitcoin prices to go up and down because I think it is a very good moment and easy to guess, just imagine if you can read the movement of bitcoin price conditions it will be easy to get a lot of profits.
To know the factors that affect the sudden price change of bitcoin is really helpful as we decide whether to sell immediately the coins we currenctly have or hold those until the time we believe bitcoin will rise based on the factors we know. Yet at the end of the day, all we can do is to adjust based on the price and current situation of bitcoin because we can do nothing despite the fact that we are aware of the factors. Which means that we are just followers of the changes that happen in bitcoin. To know the factors are just guides for our decision when trading.
I agree with you mate! You are constituting are a very good point. But then I don't know if you are pointing out the positive side of knowing the factors of sudden price change or the negativity of it.
But then, I believe that knowing the factors are helpful to speculate the price if it will either go up or go down. Through our own speculation, we will be able to create a strategic way to better decide.
