Let's do the math: A new address bought 6,277 ETH over 3 days and is currently sitting on an unrealized profit of about $477,000.
$ETH 24h trading volume: $729 million; change: +4.98%; range: 2301.46 ~ 2450.
Trading volume is the first data point for gauging the significance of news: when news really matters, volume tends to surge.
