I am extremely skeptical of any statements by anyone saying that "whales did this" or "whales did that". It is impossible to accurately associate addresses with people or companies just by analyzing the blockchain. Even with heuristics and advanced surveillance techniques, I don't believe anyone can be as accurate as they want you to believe.
I do NOT want to "associate addresses with people or companies", I DO know there are addresses with large balances, I would like to know which address is changing its balance.
It's easy to "know which address is changing its balance", but that say nothing about whales and nothing about trading. Simply stated, you cannot determine who is trading what by looking at the block chain because trading is done completely off-chain.
