Just waiting at a train station and thinking. I am of the perspective that the primary use of crypto is Bitcoin's function as a new investment technology. Something that is still young and volatile but the most accessible and liquid way the general public can invest their money in a scarce asset that is by it's very design, built to increase in price.
Everything else is speculation.
Internet of things? - Maybe, but so far away and not understood I'd rather buy a lottery ticket
Smart contracts? - Probable, but difficult to see what a world of decentralised smart contacts would look like. Take a very small part of your cash and put it into this and hope the "Killer app/game/contract" is built on your platform some time in the future.
Censorship resistant internet money? - Yes, Yes, YES!
What do you think?
