According to the monitoring of on-chain analyst @tocuee, a few hours ago, a huge amount of cold-to-hot transfers occurred in the Coinbase address, and 150,000 ETH worth nearly $550 million was transferred from the cold wallet to the hot wallet.
This huge amount of ETH was deposited 6 years ago. If calculated at the price at the time of deposit, the floating profit of this ETH is $533 million.
On-chain analyst @ai_9684xtpa said that he believed that the general cold wallet funds were transferred out to deal with large withdrawals.
