You still can use an encrypted wallet over TOR as i said above in the previous comment, and you can pretend that the widthdrawal you sent yourself from Bitstamp was made by hackers.
Do you think it is a safe method?
That's not safe, at least not as safe as it could be.
Yes, you have some sort of deniability, but it's probably not plausible (did you report the supposed theft to the police? why not?).
But your biggest problem is: they
actually do find you easily and while they don't have definite proof, they will definitely
suspect your involvedment and start an investigation. Why become a target at all if it can be avoided?
