Take a look at this: two retail miners solo-mined two Bitcoin blocks in under 7 hours
$BTC 75136.29, 24h -0.079%, 24h trading volume 1.134 billion.
It looks uneventful, but changes like this are easy to underestimate. Checking whether trading volume changed noticeably around the time the news was published is the most direct way to assess it. Is anyone around you talking about this?

Just my personal take; I may not be right, so take it with a grain of salt.
