there is no mapping to leak, there is no join between your identity and the bitcoin ledger, there may be some sites such as coinbase that can say "well coins were sent from this address controlled by Mr. Bob, to a new address". Mr. Bob says he sent it to a gambling website, exchange, merchant, localbitcoin sale, in person trade etc. After that he has no idea where it has gone or no way to link the identity of the current owner of those bitcoins, add in 3 or 4 more steps and it doesnt become difficult to obfuscate the trail enough that there is no conclusive link.

that says nothing for coins mined directly, wjere there is no link to any real world identity held anywhere, just a bitcoin payment address.
