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].
For sure Antonopoulos would make Schiff a little more interested with what bitcoin as to offer, especially on the technology side of things. He's just the dude that I highly respect and knows what he really talks about when it comes to bitcoin and other things re: economy.
