The market can be unpredictable "sometimes"? 
It can be and will be unpredictable all of the time.
I don't knowhow you get your impression but it is not possible for any market to be unpredictable all the time and major experience crypto traders can testify that they make predictions at some point which the result was 100% accurate while the result will also be contrary at some point this is what makes the crypto market to be unpredictable sometimes. It can be and will be unpredictable all of the time. It is not an impression,,, it is fact. Tell me when the market is predictable. By definition, if the market is predictable, then you know what will happen, and everyone else can also, then nobody will make a loss in those times. And everyone can make profit,,, which simply is not possible as there have to be losers for there to be winners.
100% accuracy, just read what you said and go and find me just 1 reputable trader who says this is true.
