16,369 ETH transferred from FalconX to an unknown wallet.
Such actions of "out of custody → self-custody/cold wallet" usually indicate a bullish outlook in the medium term.
Combined with the continuous extraction of over 300,000 ETH by "mysterious addresses" over the past 8 days, it resembles a unified dispatch from institutional treasury.
my take: This wave seems more like "buy and hold" rather than high-frequency arbitrage. The supply side continues to tighten.
