Technical analysis is primarily a set of tools for predicting probable price changes based on patterns of price changes in the past in similar circumstances.
The cryptocurrency market is too young to be fully trusted with technical analysis. Moreover, and probably the most important thing-the cryptocurrency market is not regulated by the laws as in the stock market and is subject to manipulation.
Market makers and big players tend to play against the crowd,so I wouldn't rely on technical analysis alone.Important news can much more accurately determine the movement of the asset price.
