On the positive side I think there's something like creating wealth through the power of imagination.

I mean 20 years ago there were no crypto currencies. Now on paper they are worth $2trn ($260 a head for the world's population). And lots of people can feel wealthy because they have $100k in bitcoin of whatever. And it can retain actual value in the sense that you can swap it for US$ as long as everyone doesn't sell at the same time. And where has the value come from - basically human imagination thinking the 0s and 1s are worth something. Which may be more sustainable than it sounds. Where does the value of fiat currency come from or the value of a painting in excess of the cost of making a copy of it?

I foresee a future where everyone is a crypto millionaire through the power of imagination. (Which would imply a 10000x form here?!)
