An Inventor of the VIX: ‘I Don't Know Why These Products Exist'

``In my wildest imagination I don't know why these products exist. Who do they benefit? No one, except if someone wants to gamble --- then, OK, just go gamble... And who exactly made money? The VXX from its inception in 2009 is down, what, 99%, even after this move... It's kind of sad that these products exist in the first place, but it's hard to stop it. If you stop this, something else will come up. Bitcoin will come up.''
