OK, suppose you have $1000 to invest, and you can only put it into Tesla or Bitcoin (and you can't adjust the rest of your portfolio to offset the investment). Which do you pick?
I would pick Bitcoin because the energy is distributed, and even though I can't see a way of benefitting from the ideas yet, I have faith that others will rigorously try and find something that works. Tesla is just a car company. (I would preferably only take small bets here.)
