The richest bitcoin address is at the time of writing worth 144,341 BTC or 162,958,687 USD. 21.62% of all bitcoins are today held in the top 100 addresses.

If we monitor these addresses, we could detect movement when these big players decide to do something, like moving coins from cold wallets to hot wallets before selling.

This way, we could know about a selloff before it's actually executed on an exchange.

For example: 1DWosvn7iEv6TUfCUXsmLqNVBZi9usEkex (worth 46000 BTC) recently moved all but 1600 of his coins. Where did he move them? If he moved them to some exchange, he might be preparing to sell.

Is there a way to know which addresses are linked to exchanges?
