Two Bitcoin whales deposited a combined 2,571 BTC (approximately $206.52 million) into Coinbase Prime within the past 10 hours, marking their first on-chain activity in three years. The dormant wallets had remained inactive since 2023 before suddenly transferring the large holdings to the institutional trading platform. Whale movements to centralized exchanges are closely monitored by market participants as potential signals of selling pressure or portfolio rebalancing by long-term holders.
