Why is it recommended to use a wallet like atomic wallet that uses/connects to the Tor network?
Like I don't get it. If I send anonymous btc (mined, mixed, or xmr transfer) to a generic address I own. How would that mean anyone could know I own it? It's not like those btc addresses save IP addresses do they?
What am I missing?
No, your ip isn't saved on the blockchain.
If you use an SPV wallet (like electrum) without tor tough, you do connect to the electrum node to broadcast your transaction. So the node operator could potentially log your actions.
