According to AltcoinGordon, Bitcoin exchange balances have plummeted to their lowest levels since late 2018, signaling a potential supply shock that could significantly impact market dynamics. This decrease in exchange-held Bitcoin suggests a trend of long-term holding, which could lead to reduced liquidity and increased price volatility. Traders should be aware of these developments as they may influence trading strategies, especially in anticipation of possible price surges due to limited supply. Monitoring exchange balances can provide insights into market sentiment and potential price movements.
