Where did the coin come from? Unless you mined it yourself, you’ve left a trail that may eventually lead to you. Even using crypto ATMs, you’re still on surveillance and hoping the tapes/drives roll over before someone comes knocking (which is a very likely bet to win), and even then, you still have a real world location to tie the wallet to because of where the transaction originated.

Anything that interacts with the real world can anchor your identity to your wallet. Travelling out of state can help obfuscate that to an extent, but a high level adversary will be able to correlate travel with that transaction as well.
