It is a fact that technical analysis and elliot wave theory do not apply in predicting Bitcoin's price. However, when we use technical indicators, supports and resistants that go back in time, 2013-2018, then you can have a very general idea of what is happening and you can conclude a price range where you expect price to move.
This is not good for those who practice day to day trading, but those who want to build a long term investment portfolio will find it very useful.
