Bitcoin and ether exchange supplies have hit historic lows, according to CoinDesk, but the old playbook that treats falling exchange balances as automatically bullish is less reliable today. More coins can sit in ETFs, custody platforms, staking structures, and institutional wallets without creating immediate spot-buying pressure.
The signal still matters. Lower exchange reserves can reduce the amount of inventory available for quick selling and can amplify price moves when demand suddenly returns. But it does not answer whether new demand is actually present, whether market makers are quoting enough depth, or whether derivatives traders are adding conviction.
A stronger framework is to treat exchange reserves as one layer of a dashboard. Pair it with ETF flow direction, stablecoin liquidity, spot order-book depth, funding rates, open interest, and whether rallies are being led by high-quality volume or thin weekend-style liquidity.
For spot traders, the risk is over-reading scarcity. If reserves are low but ETF flows are negative and perpetual funding is stretched, a breakout can still fail. If reserves are low, flows improve, and derivatives participation rises without extreme leverage, the supply story becomes more useful.

Risk notice: On-chain and exchange-balance indicators can lag or be misread. Use multiple indicators and manage position size; this is not financial advice.
