It's good to use analysis by people to predict the next market value of bitcoin but there is always one thing people need to understand. This is that, the entire bitcoin market and ecosystem is 80% unpredictable and do not really follow the analysis made by experts. You just have to be open minded in order to understand some aspects of the bitcoin market...
Predictions are not all bad at all some are useful things that you can use if you are having confusions with the market but it is called predictions for the reason that it can or may not happen at all so we have to be ready always of whatever outcome and dont rely mainly on predictions of others because it might just disappoint you. The market trend in bitcoin is way unpredictable that even the smartest cant predict it right most of the time so just do what you think is best for you and be always prepared of the worst.
