Shkreli was a small fish. There was this company that focused on buying other drug producers that had developed cure no other company were selling, after doing that they upped the prices to the skies, literally. They did this over and over again and even Wall Street got involved. Their stock rose sharply but soon skeletons started to show up from drawers. I think their stock price was over 200 at highest point and is now down to 6 dollars or so. Don't remember the name of the company, but I learned this from dirty money-series from Netflix. It was just pure greed playing with peoples lives. Crazy. You should look the episode up if you want your blood to boil.
