Yes I quite agree with your idea, however and whatever happens to Bitcoin it all depends on what most of the traders involved there do, on the other hand yes it is obvious that if indeed Bitcoin has a certain pattern then I think this is not trading because most likely the price movement will be predictable and there will only be profit in that situation while on the other hand trading is always about profit opportunities and risk of loss. So we can't make the pattern as the main point to follow because after all it is the history of the price movement that has happened in the past and because something happened exactly as you said.

But on the other hand I would not say that history is not useful at all because obviously it is something that we can combine with the knowledge we have along with what is now happening that has an influence on the price movement of bitcoin. On the other hand, I also always use that method, or that means I always look first at the last price movement before I finally open a trade, making it a benchmark to consider what decisions I will take at a certain time, even if for example in the end my prediction misses but it doesn't matter because there will always be wisdom and something that can be learned to be more developed.
