This is a good usage of crypto. Nobody knows where it came from. Until, you know, block chain analysis.
Exactly Pek, and this is why the money laundering rubbish about Bitcoin is so ridiclous, it's all done on a public blockchain so it's a pretty foolish place to commit big time crime. Throw in very sophisticated analysis of the blockchain by the chain analysis companies and it's not that hard to connect all the dots.
Does money laundering go on within Bitcoin, of course it does, but it's so minisclue it's not even worth bothering about. This point has been proved by countless government agencies both in the US and abroad.
Want to know where the real money laundering goes on? Look into how much in fines the big global banks have paid over the last 10 years for specific money laundering offences. The number I think tops $2billion in fines.
As ever, money laundering/ mafia involvement/terrorists etc + Bitcoin makes a great story to get clicks.
