I deposited over $10k in chipmixer over the onion url (chipmixorflykuxu56uxy7gf5o6ggig7xru7dnihc4fm4cxqsc63e6id.onion) on a very secure PC and clicked on withdraw. I was given a list of the private keys as usual with the amounts associated with each. Then when I checked the public addresses of the private keys on the blockchain, each wallet had 0 BTC and no incoming and no outgoing transactions.

This has never happened before after using the service dozens of times.

Chipmixer, is there a problem? Where's my BTC?
