• WLD — accumulation, $49.5M. Three buys totaling $49.5M from cold to hot wallets occurred alongside smaller round-trips. Net flow indicates accumulation by a verified whale with prior large ETH activity.
• WBTC — accumulation, $25.6M. Three internal hot wallet transfers totaling $25.6M concentrated in verified whale addresses. Counterparties and timing coincide with BlackRock and Strategy purchases reported in news.
