I'd be more interested to hear what he thinks makes for a good currency, inflation vs. deflation, freedom of transfer, protection against forfeiture, etc.
Does he also think that the US Dollar is rat poison because it's not a productive asset? He holds like $80b cash.
"But bitcoin has high fees" well yeah, there are 1,000 newer cryptos with lower fees. (and plenty of scams)
"But local stores don't use it" well yeah, nobody used credit cards in the 40s either. (and now cash is dead)
"But it's not user friendly" well yeah, neither was the internet until ~2000. (i've seen nearly zero progress in crypto here, btw)
