For what I gather in the incognito bust the cex reported him to the Feds for the amount of money he was receiving with out being able to show proof of income…

After that the Feds only traced bitcoin and what was deposited into the cex…

The Feds have not bought drugs with bitcoin…

The Feds watched the btc get washed to xmr and saw it deposited in the cex… (was he really swapping btc straight to an exchange addy or vice versa?)
