Think no more my friend! there is no exact mathematical formula that can prove Bitcoin will reach $200k by 2026 or early 2027. I wish market works on math laws and historical events but it doesn't. Years ago I was having the same thought but now mentality has changed..
The problem with mathematical series like that is that sooner or later they hit reality. Without being about series, the one who had a very elaborate prediction system is PlanB, which never tires of making a fool of itself, and we can see how it ended up.
As my last line of the thread says: "Obviously, it doesn't work this way, and there are many factors that influence the price, but it's interesting, at least for me, to look at it from a mathematical perspective", when speculating, no one is right and no one is wrong until it happens.
It is fine as a curious point of view and for debate, but you have already seen that there are several of us who are very skeptical.
