Bitcoin supply on centralized exchanges has reached a new all-time low, falling below 2.5 million BTC, marking the lowest level in nearly seven years since August 2018. This decline represents the fifth consecutive week of outflows from exchanges, reflecting increased self-custody and long-term holding by investors. The available supply on exchanges has dropped to approximately 14.5% of the total Bitcoin supply, the lowest percentage since 2018. Analysts suggest this sustained reduction in exchange reserves could lead to a supply shock, potentially impacting Bitcoin's price dynamics. However, recent data from mid-July indicates a sharp reversal with a surge of 14,400 BTC inflows into exchanges, the largest in weeks, coinciding with a recent price dip and signaling possible upcoming volatility in the market. Bitcoin exchange reserves are now at their lowest level since the cryptocurrency was priced around $15,000.
