Peter Schiff has issued a warning about a potential decline in Bitcoin's price, highlighting weak fundamentals as gold and silver experience significant gains. Bitcoin experienced a 17% drop in November, marking its worst monthly performance in seven years. In contrast, gold and silver have surged by 60% and 95%, respectively. Schiff criticized Bitcoin for its lack of intrinsic value and fragile liquidity, emphasizing the stability of tangible assets like gold and silver. He also referenced historical patterns where Bitcoin often ends December negatively following a poor November. The current fear and greed index indicates increased market anxiety.
