Exchange reserves Bitcoin
The total amount of BTC held on all major crypto exchanges. A decline in reserves means that owners are withdrawing coins to cold wallets, reducing the supply available for sale.

Why are exchange reserves important for a trader?
Exchange Reserve — is an on-chain metric showing how much bitcoin is stored in wallets owned by crypto exchanges. When investors are confident of growth, they withdraw coins from exchanges to their own wallets (cold storage). When they want to sell, they transfer them to an exchange. This makes reserves a leading indicator of selling pressure.
In October 2020, exchange reserves began to plummet—from 3.1 million BTC to 2.7 million in three months. This was one of the early signs of a bull run: large holders accumulated coins, removing them from the market. Bitcoin rose from $11,000 to $29,000 by the end of the year.
The opposite process—a buildup of reserves—is often a bearish signal. In May 2021, before the collapse from $57,000 to $30,000, several hundred thousand BTC entered exchanges. This was evident in the data a few days before the move. The combination of growing reserves and negative fundamental data (China banned mining) triggered a downward cascade.
How to interpret changes in reserves
Reserves are declining
Holders are withdrawing BTC from exchanges into cold storage. The supply for sale is decreasing. This is interpreted as a bullish signal—long-term holders are not planning to sell.
Reserves are growing
Coins are flowing into exchanges. The increased supply is creating selling pressure. This is a bearish signal, especially if the inflow increases sharply over a short period of time.
A sharp jump in a day
A large tranche of BTC has entered the exchange. This is often a major holder preparing an OTC sale or profit-taking. This could be a harbinger of a local correction.
Long-term downtrend
A sustained decline in reserves over months is the strongest bullish signal. This indicates structural accumulation, not tactical movement. This was observed in 2020–2021 and late 2023.
