Whale Moves 20.43 BTC After 15.4 Years, Booking ~$1.72M Profit

The headline number is the holding period, not the profit: coins dormant since the Mt. Gox and Silk Road era are now liquid, and the wallet's history with both suggests early-exchange or marketplace exposure rather than an ordinary long-term saver. That matters because it puts a small but symbolically loaded slice of old supply into circulation at a moment when the market already watches every aged-wallet move for signs of broader distribution. Whether other long-dormant addresses follow is the open question; a single 20 BTC transfer is noise on its own, but a pattern would not be.
