A Russian man has just been arrested in Greece after being indicted by the US for money laundering. Alexander has mixed over $4,000,000,000+ worth of Bitcoins through his exchange, BTC-e (which has now been shut down) among other charges. Mainly he's getting screwed because of the leniency his site placed upon KYC and AML laws. (*AML - Anti-money laundering *KYC - Know your customer)
