Bringing crypto to mars! What a question.

No serious, I have no idea. And just because he holds a book about crypto in his hands, doesn't mean he plans to use or build something crypto related. Maybe it's just curiosity or someone gave him that book as a present.
Ha ha yeah. Forget about the moon, we can just go to mars right? Yeah he might not be involved in any project yet but its good that he started to get interested and also that this way he might have promoted the book to new people. Would be nice though to have him in the crypto community!
