According to Crypto Rover (@rovercrc), both Bitcoin and Ethereum balances on major exchanges have reached historic lows as of June 1, 2025 (source: Twitter). This trend indicates a significant reduction in available supply for spot trading, which can often precede sharp price movements or increased volatility. For traders, such low exchange reserves suggest a potential supply squeeze scenario for BTC and ETH, historically associated with upward price pressure when demand rises (source: Glassnode data referenced by Crypto Rover). Monitoring on-chain flows and exchange wallet balances is now critical for anticipating possible breakout moves in the crypto market.
