If it's ever to go relatively mainstream then the price must rise by orders of magnitude for it to be usable by a significant number of people.

The last few months have been an amazing time to buy in. 12-18 months ago it still would've seemed like it could die at any moment. Fast forward to today and it's being backed by some serious investment, probably tens of thousands of extremely clever people and it's being discussed at the highest levels.

Despite all this, very few people in the world have any or truly understand what it is yet. That's a dreamlike combination for future growth but it will take a few years yet.
