if you can get 10 cents of extrinsic value on VIX calls that expire in 1 week < I have a bridge to sell you .maybe you can get 10 cents if they expire in a day..but no way if they expire in longer than a week. That would be the equivalent of 'going long the vix' which is impossible .
This just proves how little you know. VIX options do not track the VIX. I think that is your problem.
