Guys, try to stick with questions that he cannot answer without actually showing proof.

Don't bother posing questions that will simply allow him to waffle on about how the big bad 'legal' department ruined his dreams, or that there was a concerted conspiracy to destroy his 'legitimate cryptocurrency business which would have cured the world of [insert ailment here]'
Try for things like, "Why have you repeatedly made absolutely false claims towards your altcoin clone having cutting-edge innovative tech, when it is just a regular Proof-of-Stake coin and that an analysis of the Github has shown repeated pushes of code which had minor cosmetic changes removed and then replaced, as though to imply that there was regular development work being done on it?"
He would probably just answer that saying "We tried to have those features at Launch but came upon a development snag, those features will be in there soon (TM)"
Nice, but it would probably be better stated as "Can you prove, showing development progress, that there was, and is, actual work ongoing as to the "innovative" features of the coins. Such as Hybrid Flex, Voting system, etc etc. This should be no problem to prove, as it is going to be Open Source anyhow in the end. If they don't have anything at all, or very little developed... well, he lied.
Least this way he must show proof to answer the question. Or evade it by saying it is NDA or some BS.
