Bitcoin has maintained its position above $78,000, leading some experts to suggest that the cryptocurrency winter may be over. According to NS3.AI, Michael Saylor expressed optimism about Bitcoin's recovery, indicating that the prolonged downturn might have ended. However, Jason Fernandes noted that despite Bitcoin's improvement, altcoins continue to show signs of weakness. Mati Greenspan added that the recent movements since the October 10 flash crash appear to be a pullback within a larger bull market trend.
