If you bought those coins then your going to end up screwed in the end. Sheep Marketplace was already being watched by multiple agencies and since they were robbed i can guarentee that when they find him they will be pissed they cant claim those coins for themselves
You are correct about risks. However, my largest concern is the anonymity of my customers, not of myself. I thoroughly launder all stolen bitcoins to prevent tracking of transactions. My personal safety is under control, because I work with Satudarah to ensure my anonymity during customer meetings. I am also paying 'Ndrangheta for protection.
