You cannot easily change Peter Schiff's mind when it comes to cryptocurrencies and his stand with gold. Knowing that the dude is a gold bug for a few decades now, I don't think no key points would ever be laid down on that debate that would convince him that bitcoin is also the real deal and not just gold. But considering the experience of these two with the two assets that they have been working on, this might just be a good debate with some interesting points to be taken.
At least now it's someone with decent knowledge. I've heard Arthur Hayes lost his debate with Nouriel Goubini really hard. I've always wished Andreas Antonopoulos would school those critics though. It would be very one sided for sure. Unfortunately he's just uninterested[1].
There must be one reason why he is uninterested and is probably the same reason why you think that he is smart enough to give classes to those critics, he must be seeing that it is a completely and huge waste of time.
The quality of one debate will normally be decided by the quality of the words of the less skilled speaker, if you argue with someone not so smart or dumb then the quality of the debate will be almost childish, if not worse.
However, if he did find a man or woman with enough culture i'm sure that he would totally do it if there is a good reason to do so. If it's another teacher it would probably be better. Otherwise, why wasting time doing it?
