A wallet described as linked to ShapeShift added 668 Ethereum in the past hour for roughly $1.35 million, according to Onchain Lens (blockchain wallet tracking service). The address now holds 139,882 ETH with an estimated value of about $281.7 million. Large purchases by a whale (wallet holding a very large amount of crypto) are often watched by traders because they can signal concentrated accumulation activity on the Ethereum network.
