Bitcoin's price has rebounded above $81,000, but its reserve on Binance has surged to 702,900 BTC as of September 19, marking the highest level in 2026. This increase in exchange reserves is raising questions about whether the recovery is backed by enough spot demand and is painting a bearish picture for the asset, as it indicates more Bitcoin is potentially available for sale. Data shows Binance has recorded rising daily net inflows since late August.
