Read this fascinating
story of a young bitcoin fellow named Jimmy who stole from silk road. The site happened to have a glitch and Jimmy withdrew 50,000 btc. The owner of silk road contacted him when it appeared to him, that 50k btc disappeared from his wallet due to the glitch, but Jimmy afforded him no help. Later, Jimmy transferred $800 to a KYC enabled exchange, and the cops were able to link it back to the stolen 50,000btc from silk road. How possible is this?
This is a simple thing and anyone following the wallet that the stolen funds was sent to will have follow up of whoever and where ever the bitcoin is sent to, so this should not be a misery to you at some point because at some point you need to give up some privacy anytime you chose to use a centralised platform like exchangeszl, and from this user incident, you can see that the coin was traced to his kyc exchange wallet and he was caught.
Bitcoin is like every other currency, once you have commited a crime by taking coins that is not your own, the authorities will have to right to do a fosice analysis on your wallet and sometimes, they can request for other information from exchanges.
