"Like most hedge fund managers specializing in cryptocurrencies, Samani constantly tracks trading activity of addresses known to belong to the biggest investors in the coins he holds. (Although bitcoin transactions are designed to be anonymous, each one is associated with a coded address that can be seen by anyone.) When he sees activity, Samani immediately calls the likely sellers and can often get information on motivations behind their sales and their trading plans, he says."

Is there any resource to find the list of the biggest investors in the coins? Or any addresses that are known as "Whales?"
