Innovation doesn't come from the big company. It never has and never will. Innovation is something new that looks crazy at first glance. It comes from the 19-year-olds and the start-ups that no one's heard of.

Most of the big breakthrough technologies/companies seem crazy at first: PCs, the internet, Bitcoin, Airbnb, Uber, 140 characters.. It has to be a radical product. It has to be something where, when people look at it, at first they say, ‘I don’t get it, I don’t understand it. I think it’s too weird, I think it’s too unusual.’

It was a joke, okay? If we thought it would actually be used, we wouldn't have written it!

Only two people have been on the cover of Time Magazine in bare feet. I'm one, the other is Gandhi.

There will be certain points of time when everything collides together and reaches critical mass around a new concept or a new thing that ends up being hugely relevant to a high percentage of people or businesses. But it's really really hard to predict those. I don't believe anyone can.

The gulf between what the press and many regular people believe Bitcoin is, and what a growing critical mass of technologists believe Bitcoin is, remains enormous.

Innovation accelerates and compounds. Each point in front of you is bigger than anything that ever happened.
