The interviewee (Schiff?) did present a decent argument that Bitcoin is currently based around faith in the crypto, and there isn't really any denying that as Bitcoin stands now. It is also largely speculative, and you can watch the entire crypto market for a few days and see how that is an accurate statement. Keiser(?) had his points too, but it really just looked like a goldbug v cryptobug debate. I don't know either of them beyond this clip, at least not in any capacity I remember, so take my opinion with a grain of salt.
Yeah man at first I thought Schiff did not know about Bitcoin, but apparently he is very smart and knows about it he just doesn't like it or feels like it won't work. He does give some good points... although I feel like Kaiser still won.
