Binance’s Bitcoin Reserves Hit a Two-Year High. Santiment Says Exchange Balances Told You Nothing All Summer.

Binance just hit a two-year high in Bitcoin reserves, which sounds alarming until you look at what exchange balances actually predicted about price all summer long.

Binance’s Bitcoin (CRYPTO:BTC) reserves have climbed to their highest level in two years, a move that might normally be read as a warning for BTC. More Bitcoin sitting on an exchange can suggest investors are preparing to sell, but Santiment argues that exchange balances offered little useful direction throughout the summer. 

We look at why Binance’s holdings have risen, what Santiment found in exchange data over the summer, and whether the latest move points to selling pressure or something else.

Why did Binance’s Bitcoin Reserves Hit a Two-year High?

Binance’s Bitcoin balance rose by about 77,000 BTC since late April, pushing its total reserves above 693,000 BTC. Darkfost’s data, cited by WuBlockchain, puts Binance’s holdings at their highest level in two years and roughly 30% of the Bitcoin held across major exchanges.

The increase began after Binance’s SAFU fund announced plans to acquire around 15,000 BTC as part of a $1 billion allocation, with those purchases going directly into Binance’s holdings. At the same time, some Bitcoin holders moved coins from self-custody devices to exchange wallets for security after the ColdCard hardware wallet incident. That shift can increase an exchange’s reported reserves without showing that those holders intend to sell. 

Binance’s increase looks unusually large when compared with the broader exchange market. CryptoQuant tracked Binance’s reserves rising from roughly 616,000 BTC in April to about 667,500 BTC by mid-August. Darkfost’s more recent figures, cited by WuBlockchain, put the balance at 693,000 BTC by early September.

Across all exchanges, the increase has been smaller. Santiment’s data shows that the total Bitcoin supply held on exchanges has risen by about 45,000 BTC since May. Binance added roughly 77,000 BTC during that period, meaning a large share of the Bitcoin moving onto exchanges ended up in Binance wallets this summer.

Why did Exchange Balances Fail to Predict Bitcoin’s moves?

Bitcoin held on centralized exchanges increased by around 45,000 BTC, or about 3%, between May 11 and September 8, according to Santiment. Over the same period, Bitcoin’s price moved much more sharply, trading near $81,700 in May before falling to $58,562 by June 30 and recovering to roughly $79,000 by early September. That put the move from the June low to the early September price near 40%, while exchange-held Bitcoin stayed within a band of about 54,000 BTC, or roughly 4% of the total supply held on exchanges.

The numbers show why exchange balances offered little help in predicting Bitcoin’s moves this summer. Santiment described exchange balances as a widely tracked metric that failed to provide a useful signal during the period.

Exchange-held supply fell from about 1.337 million BTC on June 12 to 1.304 million by July 28, a decline of roughly 33,000 BTC. Normally, traders could read that decline as bullish because fewer Bitcoins on exchanges means fewer coins readily available for sale. Bitcoin continued falling through most of that period and reached its June 30 low anyway.

The same problem appeared when exchange reserves recovered. Supply climbed back to about 1.332 million BTC by mid-August, recovering 84% of the earlier decline. Traders could have interpreted the increase as bearish because more Bitcoin was available on exchanges, yet Bitcoin held roughly flat and later recovered.

ETF buying also helps explain why exchange balances can miss important sources of demand. Santiment has noted that spot Bitcoin ETF issuers largely acquire coins through over-the-counter deals with miners and existing large holders. Those transactions do not pass through public exchange addresses, so ETF demand can remain strong even when exchange balances show little change.

Will Binance’s Bitcoin Reserve Surge Affect BTC Price?

Binance’s reserve surge puts more Bitcoin on one heavily used exchange, but the increase does not, by itself, show those coins are about to be sold. ColdCard-related transfers and SAFU’s purchase program account for a meaningful share of the 77,000 BTC added to Binance, offering explanations separate from selling plans. At the same time, Santiment’s summer data shows that exchange balances across the market did not consistently track Bitcoin’s price, so Binance’s latest reserve increase needs the same careful reading.

Binance holding more Bitcoin than it has in two years is therefore worth tracking alongside stablecoin supply, derivatives open interest and ETF flows. Those measures can provide more context around why Bitcoin is moving onto exchanges and whether traders are preparing to sell. A Binance reserve increase on its own does not provide enough information to forecast Bitcoin’s next price move.
