Looks like word twisting to me...he said "where BTC has failed" and you know there is a specific meaning to that statement and I never seen him say its not viable. Keep painting with that broad brush

“I don’t believe that the bitcoin has a chance to be a viable currency,” said Josh Garza, chief executive of GAW Miners, a cryptocurrency mining equipment retailer and consultancy. “One of the big confusions behind the bitcoin is that the great thing about the bitcoin is not the brand or the coin itself, but the technology behind it. It’s the blockchain that makes bitcoins great.

“There will never be a time that a normal consumer will be okay logging into their bank account and seeing a different amount in their account than the day before without spending any money. The viability of the bitcoin will never make the virtual currency palatable to the average American, when other platforms, such as PayPal, offers what bitcoins offer without the value fluctuations. Once the hype dissipates, the impracticality of the bitcoin will doom the cryptocurrency. But the blockchain will remain; it’s the future of how value will be recorded and shared.”
