Bitcoin reserves on exchanges fall to lowest level since 2023

Crypto exchanges are emptying their bitcoins at a rate rarely seen in two years. In less than three months, nearly 100,000 BTC left Binance, OKX and Gemini, or more than $8 billion removed from the market. As available supply contracts, long-term investors are discreetly strengthening their positions. This combination of dwindling reserves and returning demand is starting to fuel speculation around a possible supply shock for bitcoin.

8 billion dollars leave crypto platforms

Bitcoin reserves held by large centralized platforms have fallen sharply in recent weeks. According to data from CryptoQuant, almost 100,000 BTC withdrawn from Binance, OKX and Gemini in less than three months, or more than $8 billion at current market prices.

Binance is seeing the biggest decline, with reserves falling from around 670,000 BTC on February 21 to almost 620,000 BTC on May 7. OKX saw its holdings decline from 132,000 BTC in early March to around 102,000 BTC, while Gemini fell from 114,800 BTC in early February to around 95,000 BTC. Analyst Amr Taha estimated “that a synchronized drop on several platforms has more weight than isolated releases on a single exchange”.

The main movements observed on the exchanges are as follows:

• Binance: reserves drop from 670,000 BTC to around 620,000 BTC;
• OKX: decline in assets from 132,000 BTC to almost 102,000 BTC;
• Gemini: reserves drop from 114,800 BTC to around 95,000 BTC;
• Cumulative exits: nearly 100,000 BTC withdrawn from the market;
• The estimated value of the withdrawals: more than $8 billion.

This coordinated reduction in reserves also comes at a time when OTC balances are contracting rapidly. Data from CryptoQuant shows a 30-day OTC change of -24,940 BTC, while this indicator still showed +25,300 BTC on February 8 after bitcoin fell towards $60,000.

For Amr Taha, this scarcity of available supply could amplify market reactions during a massive return of spot demand. The analyst emphasizes that “fewer coins available on trading platforms can amplify the price reaction when spot demand returns strongly”.

Long-term investors strengthen their positions

In parallel with this drop in reserves, wallets identified as accumulation addresses have accelerated their purchases of bitcoin. Data from CryptoQuant indicates that these addresses held 264,000 BTC on May 6, up from 164,440 BTC on April 23. This level had even fallen back to close to 100,000 BTC in mid-March after having exceeded 205,000 BTC at the beginning of February. This dynamic reflects a clear resumption of accumulation by long-term investors during bitcoin's rise towards $82,800.

The derivatives market is also showing a change in sentiment among traders. On Binance, seven-day net taker volume increased from around -$1 billion at the end of March, a sign of seller dominance, to +$2.63 billion on Thursday, indicating a marked return of aggressive buyers. This development no longer only reflects a reduction in the supply available on the platforms, but it also indicates growing confidence among market participants in the ability of bitcoin to maintain its current trajectory.

This combination of massive outflows from exchanges, drop in OTC reserves and return of accumulation could become a key factor for the market in the coming weeks. If institutional demand continues to grow while liquid supply shrinks, bitcoin could operate in an increasingly tight liquidity environment. The next market movements will now depend on the ability of buyers to maintain this pressure in the face of a quantity of available BTC which continues to contract.
