Could we soon expect $ETH at $4000?

Blackrock has bought $ETH for nearly 1 billion dollars in the last 2 weeks. Such companies do not make reckless purchases of such amounts. There must be some reasons for such actions that we are not aware of right now.

The question remains open: should we follow this whale? It's up to everyone to decide, but I would be glad to hear your thoughts in the comments.
