Update: When you wake up, you start selling and selling mode 💨
Two days later, the "2020 $ETH giant whale with a cost as low as $588" was suspected to sell 1,000 ETH (about $1.65 million) again 12 hours ago. If sold, it will make a profit of $1.064 million.
Fortunately, the giant whale only has 1,018 ETH left, which will not cause excessive selling pressure on the market.
