Bitcoin (BTC) has pushed back above its previous high near $87,000, and the recovery is now visible in a closely watched supply metric: the amount of coin still parked on trading platforms. Aggregate exchange reserves fell to roughly 2.68 million BTC as of Saturday, October 3, the lowest reading the dataset has printed in three years.

The figures were reported by COINOTAG on October 3, 2026.

What exchange reserves measure

Exchange reserves represent the total balance of bitcoin held in wallets attributed to centralized trading venues. The metric rises when users deposit coins to sell or trade, and it declines when holders withdraw funds to self-custody or to arrangements outside exchange control. Because coins held on exchanges are generally the most immediately available for trading, reserve levels are commonly used as a gauge of how much supply sits on venues at any given time. A lower reserve level therefore corresponds to a smaller pool of coins positioned on centralized platforms for immediate trading.

A three-year low

The latest reading of approximately 2.68 million BTC is the lowest recorded in the tracked series in three years. It indicates that a progressively smaller share of bitcoin's fixed supply of 21 million coins is held on trading platforms at a point when the price has moved back above its prior high near $87,000. At that level, on-exchange balances amount to roughly 12.8% of the 21 million cap.

Exchange reserve data is aggregated from balances in wallets attributed to major centralized platforms and updates as those balances change. Deposits to and withdrawals from exchange wallets are recorded on the Bitcoin blockchain, making reserve levels among the most transparent recurring metrics in the industry. Because the series updates as balances shift, subsequent readings will show how on-exchange holdings evolve from the three-year low.
