Thanks Joel_Jantsen, NotATether, ETFbitcoin, DaveF.


Please read this update to find your answers of any questions:

It's a Bitcoin mixer. They have coinjoin and advanced feature of mixing bitcoin. The audit job is to try to track back the mixed funds.

You all must be familiar of coinjoin so nothing new to explain.
Their advanced feature is to mix your bitcoin with XMR and then from XMR to bitcoin. You don't need to do it by yourself, when you chose the advanced option then the system does it for you. At least this is what I understood.

I guess now you have better idea.

Please response again and I will share the thread with my client so that they can receive your input to accept your suggestion or even give the job to check things.

Cheers,
