This is very interesting comparison of bitcoin price verses addresses holding more then 10k$ worth of bitcoin.
You can see when price of bitcoin touched 69k$ on 11 Nov 2021, the addresses have gone done. That means Whales were in selling mood at that time. Now as price has gone down, whales are once again accumulating bitcoins.
Key Takeaway: whales are called whales because of this reason.
