From the current situation, it is highly likely that this batch of addresses, which created ETH through BitGo and then heavily accumulated it, belongs to Bitmine (BMNR).

In the past 8 days, these addresses have accumulated 293,186 ETH through institutional platforms such as FalconX, Galaxy Digital, and BitGo, worth $1.24 billion.

Currently, the only entity that matches this amount should be Bitmine (BMNR): they announced that they have increased their holdings by 317,000 ETH in the past week, and currently hold 1.15 million ETH.
