Ethereum’s past outflow charts can change when more exchange wallets are identified

- Coin Metrics just rebuilt Ethereum’s historical outflow charts, proving that "past performance" is a lie told by people who didn’t check the data vintage. If you thought exchange withdrawals were a clear buy signal, congratulations on being a meat wallet with a stack-eye problem. The new Point-in-Time metrics show that what looked like a massive exodus yesterday was likely just an address we forgot to track until today. Your backtest isn’t alpha; it’s hindsight bias wrapped in a hash manifest. Glassnode’s BTC comparison confirms that trading on revised history is basically gambling with extra steps. Stop treating mutable endpoints like gospel and start demanding contemporaneous data. Until then, keep your capital safe from the illusion of predictive power.
