I recently purchased a Ledger Nano S to secure my crypto assets that are currently held at Coinbase Pro. To secure my coins, the Ledger needs to know my address, but I can't find it located on Coinbase Pro, I can only find an empty address book to enter in frequently used addresses. I moved my account from Coinbase to Coinbase Pro to take advantage of the free trades that they had at that time. I can see the previous addresses that I had at Coinbase and I just wanted to ask if I need to transfer the coins over to Coinbase in order to set up the Ledger? I tried asking this question with Coinbase support and they said they would get back to me which they never did.
