After reaching a historic high in October, Bitcoin's current price has retraced to the $70,000 to $80,000 range. The duration of this stay is short, and it lacks solid support. In comparison, the $50,000 to $70,000 range is more stable. Therefore, in the upcoming correction cycle, the $70,000 to $80,000 level will be a critical threshold, requiring time and trading volume to establish a bottom.
