My opinion is that John Oliver is most likely "incompletely informed".
Does his concern that EOS being valued at over $1Billion when the platform has no working prototype make sense and have merit? Logically, yes.
A company with a dream isn't worth the same as a company with an active and useful platform.
Does EOS have the potential to be worth $1Billion or more? Absolutely.
And I think that if it's possible, @dan will do it!
