Some of the primary arguments he uses against Bitcoin are actually its strengths. Fundamentally, Bitcoins will be in higher demand than dollars because their value will continue to rise instead of fall. This means that goods and services as priced in bitcoins will be discounted compared to dollars, driving their adoption. You can see this same dynamic at work in black markets around the world where the USD is the de facto currency vs the highly unstable local currency.

It's all about the "reserve currency", which is the currency that sellers around the world prefer to receive. If bitcoins are more attractive to sellers because of built-in deflation then they'll not only accept them but offer their products at a discount to get them. All of this creates an ecosystem and drives adoption, it does not make the currency a scam as he implies.
