Being a co-founder of the internet company I work for? As much as I respect my company, it's no Bitcoin.
There are a lot of people and companies worth over 100 million dollars. I only know of one revolutionary crypto-currency.
Or the seventeen others founded on the same technology. It's important to distinguish the Bitcoin software from the particular block chain in whose private keys naive people are now speculating.
Selection bias. You only know of one popular revolutionary cypto-currency. There are loads of companies worth $0 (or much less than $100M)
Popularity is essential to 'revolutionary'-ness. It's not revolutionary if no one uses it
Winning the Nobel in physics, or winning one of the Clay Mathematics prizes.
The Nobel prize is just around $1 million.
Really? Oh, but you can win them multiple times. Simply achieve 100 Nobel Prizes (or merely 97 if you resolve P?=NP, the Navier Stokes Equation, and the Riemann Hypothesis), and you will have made a similar contribution as Bitcoin or jQuery. That's not counting, of course, the millions you'd be raking in as a tenured professor in the meantime.
