The blockchain is public and immutable. There is no privacy. Every transaction of every coin everywhere is completely visible. Even if you run BTC through a tumbler...the overall flow of BTC is going to be moving towards whichever wallet holds it at the end of the chain when a physical transaction takes place. At which point if the physical transaction is picked up, the entire chain unrolls back to every initial source.
