Bitfinex: Bitcoin Whales Add 270,000 BTC in 30 Days as Exchange Balances Hit Lowest Since 2017

Bitcoin reserves on exchanges reflect the supply immediately available for sale, making them an important gauge of selling pressure and investors’ willingness to hold. Reserves at major exchanges including Binance, OKX and Gemini have now fallen to their lowest levels since 2023, indicating that more holdings are moving into private wallets and reducing liquid supply in the near term.

Nearly 100,000 BTC flowed out of major exchanges over the past three months, valued in the report at about $8 billion. Holdings in accumulation addresses rose by more than 60% over the same period. Exchange reserves had reached a two-year low as of the latest tally, suggesting a stronger investor preference for long-term holding, although tighter supply could also amplify price volatility.

CryptoQuant’s Binance on-chain data use the Exchange Whale Ratio—the share of total deposits accounted for by the 10 largest inflows—to gauge potential selling pressure from large holders. The ratio briefly topped 0.60 in early February 2026, coinciding with Bitcoin’s pullback that month. The price subsequently held within a $65,000–$72,000 range, making fund flows a key indicator of the direction of the next breakout.

As of March 11, 2026, the 14-day moving average of Binance’s whale ratio had fallen to about 0.45, while net exchange flow dropped to negative 1,151 BTC, indicating that withdrawals exceeded deposits and fewer coins were available for sale. Maartunn said the futures-to-spot volume ratio rose to about 5.3, its highest since October 2023. If $70,000 turns into support, the price could reprice rapidly, though $72,000 remains resistance.
