That's simply a bet. Let's however suppose you had a mathematical formula that showed conclusively that the price will have no support above $3,000 and will fall from its current value of $7,200 (ETA now $7,050) down to that lower level. Assume that anyone could access your formula. What would holders do with this knowledge? They would sell or go short, anticipating whatever timescale your formula showed, thereby invalidating it. If the formula indicated that an attempt to hold the line at $3,000 would be effective only temporarily, the attempt wouldn't be made at all, thus invalidating it once more.
That's why these things are unpredictable even in principle. All predictions, even mathematically correct ones, are self disconfirming as soon as they become known.
