Hi guys, I have a noob question and it would be nice if someone could explain this to me.

I'd like to understand at what part of the below process my coins will get anonymous.

I have a Cryptopia acc with a known public key and then I decide to send all my Sumokoins to my wallet. How my details can be 100% anonymous if the address my coins came from can be checked in the blockchain?

I hope this makes sense. Thanks
