I like to watch women's MMA more than men fighting because they always do their best and fight hard.

When I started, athletes fought for honor, respect, philosophy.

I wanted to train jiu-jitsu instead of capoeira because the mat was soft. It was better than training capoeira on the hard floor. I started reading jiu-jitsu magazines, reading about the world champions, and becoming one of them became my goal.

I've never had any fear in my entire career.

I have such strong beliefs. No money or anything could change that.

There are very few fundamental shifts in global infrastructure that can happen in our life times. The financial infrastructure is one of them, and the Blockchain is changing the way we think about the transfer of value.

Rather than being an impediment, NASA can and should be the driver of commerce, the provider of the technology necessary to make some big money in space. The truth is that private enterprise already has a huge presence up there.

We're trying to make money, trying to add a zero onto our net worth.
