Well written truth is, when it comes to Crypto at I use to say we can't be 100% wrong or right. Sometimes we tend to be permutative or predictive as a result of charts and patterns but then our expectations can be cut short. We don't really know the bottom and we don't know the highs, we just well or buy when we perceive or deem it to be correct. In the long run it boils down on luck rather than our ability to make the right decision.
To my opinion, crypto trading is the combination of luck and experience. Charts are good but not workable always.
