Bitcoin is experiencing a pivotal week as 2025 draws to a close, with its price struggling to surpass the $90,000 mark despite increased activity from large holders. The cryptocurrency's volatility has been heightened by options expirations, raising concerns of a potential decline towards $80,000. Meanwhile, the Bitcoin/silver ratio has decreased by 67%, indicating relative weakness against precious metals. In a sign of bullish sentiment, Bitfinex long positions have reached a two-year high, suggesting optimism for Bitcoin's performance in 2026. However, analysts remain divided, with some predicting a rebound to $100,000, while others caution about a possible drop to $72,000.
