Absolutely it can br tracked. That's the benefit of having an open ledger system in place. We can track each and every transaction.
You can track the coins as they move across the blockchain, but as an individual, you can't associate them with a real person unless you know his address/addresses or he mentioned it somewhere. Blockchain analysis companies can help in tracking the coins as well as centralized exchanges if they get funded from one of those addresses and the users performed KYC verification. But you as an individual can't do much about identifying the owners even if it's a public ledger.
