[Analysis: Bitcoin Market Sentiment Remains High, Potential for Further Upside] According to the latest analysis report released on May 4 by BIT independent analyst Markus Thielen, the Bitcoin Greed & Fear Index is currently at a relatively high level but has not yet shown signs of a 'pullback.' Typically, a sentiment pullback often signals the arrival of a short-term cyclical peak. The report highlights that the 20-day moving average of this index can effectively capture the natural rhythm of market fluctuations between optimism and fear, indicating that changes in market sentiment require time. The best investment opportunities usually arise when sentiment is at an extremely negative stage, rather than at high levels. Currently, as the index continues to rise, Bitcoin may still have further upside potential until market sentiment turns negative and becomes a resistance. The analyst advises investors to monitor changes in sentiment indicators to assess market trends.
