The prediction method of "marking the boat to seek the sword" forecasts the bottom price of BTC in this bear market: the previous bull market peak was around 70,000, and this bull market peak is around 130,000, which is roughly a doubling. The next bull market peak should theoretically be less than double, so let's be optimistic and estimate around 250,000. The previous bear market low was around 15,000, with a high near 130,000, roughly more than 8 times. Therefore, in the next bull market, the low point is expected to be reached with fewer multiples; assuming 6 times, the low point of this bear market should be approximately 25,000 / 6 = around 4,200.
