That whale sold 80kBTC through Galaxy Digital, meaning Galaxy has all the details about that whale's identity. Because they are a New York based financial company, they comply with legal regulations such as AML. They will not help someone sell bitcoins if they do not know the origin of those bitcoins and the identity of the owner. So I believe we have a chance of knowing the identity of that whale, which will be revealed at some point in the more distant future, not now.

By the way, I also believe this is the reason why bitcoin price corrected to $115,000 last week.
