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
Here is the CryptoNote whitepaper, the answer may be in there.
https://cryptonote.org/whitepaper.pdfWhen I use a blockchain explorer to check my Sumo address nothing comes up.
Sumokoin's addresses are stealth addresses (a cryptonote feature). A recipient can never know who send the coins unless told otherwise, this is why cryptopia is using a payment id to discern which deposit belongs to which account.
Please, however, dont confuse this with the subaddresses feature (or ghost addresses as we like to call them) its a different thing.
EDIT: Here is a very good explanation (though quite technical) from an XMR user
