I agree with Jiang's prediction on the timing of BTC's bottom. He uses mathematical modeling principles for his analysis, while I base mine more on BTC's cyclical data and macroeconomic conditions. The bottom price is estimated to be around $45K. Jiang Zhuoer's perspective: This BTC bear market will bottom out between October and December 2026, with the bottom price ranging from $42K to $44K. The principle is similar to a ball bouncing on the ground, where each bounce decreases in amplitude. As BTC's total market cap increases, its volatility decreases, resembling the behavior of the ball. This model's accuracy in predicting time is greater than its accuracy in predicting price. Considering that mNAV bottoms out six months ahead of the coin price, the prediction is as follows:
