And no, that's no new whale and no older whale, that's Coinbase (the company) wallet and they are just moving funds to a new adress.
If you don't mind my asking, how can one deduce the specific exchange an address belongs to?
I'm aware it's possible to use available blockchain activity to recognize addresses belonging to exchanges and individuals alike, but I'm not sure how to identify which particular exchange the address belongs to.
My best guess is that some exchanges have addresses which have been made public at different times.
