BTC's upcoming wide-range fluctuations and unilateral downtrend scenario analysis: (1) This drop to above 61,500, followed by another rebound to around 66,500, and a third attempt to test the previous high near 67,500; (2) BTC's price fails to break through three times—once, twice, and thrice, leading to exhaustion. Subsequently, it’s likely to drop to test the 60,000 level, which could evolve into a unilateral downtrend, falling to the 52,000–54,000 range; (3) A drop to the 52,000–54,000 range would essentially mark the final leg down. Unless an even more severe black swan event occurs, pushing the price to around 48,000, the area above 50,000 will likely be the major bottom price for this bear market.
