stolen funds can always be laundered easily enough
Yes you could mix stolen coins,
but at the end of the day someone somewhere is going to get tainted coins. Perhaps not the thief or scammer.
There is no such things as tainted coins.
Let's define "tainted coins".
Coins that can be linked to a theft or scam.Now there is such thing as that because if businesses/exchanges decide not to accept those coins as "legitimate"...now you have tainted coins.
It may not be ACTUALLY tainted, but the fact that coins came from a particular address of a scam/theft ...does imply they can be viewed as TAINTED.
remember evolution and btc-e? Just a precedent that was set.
Didn't MTGOX do the same thing with bitcoinica?
