Binance’s Bitcoin (BTC) reserves have climbed sharply in recent months, reaching a two-year high and raising questions about whether some of the coins could eventually add selling pressure to the market. In a detailed tweet Thursday, CryptoQuant analyst Darkfost said Binance now holds more than 693,000 BTC, accounting for roughly 30% of the Bitcoin reserves held by major cryptocurrency exchanges. The exchange’s holdings have increased by about 77,000 BTC since late April.
