I’m into bitcoin for two main reasons:
Public key encryption is freaking cool on its own. Using it as a way to create a trust-less currency is mind blowing and exciting.
The implications of immutable information used as currency is also mind blowing and exciting. It’s almost certainly the first objectively finite store of value. So the value of everything else has to reset itself to that in the end. That’s super fascinating, and I love exploring all of the impacts that will have on the world. I don’t even think all of the impacts will be good. Some will be bad. But it’s fascinating to learn about.
The fact that this is likely the best investment we’ll see in a lifetime is honestly secondary to me. That’s exciting, too, for sure. But not as exciting as the first truly immutable store of value. That’s gonna be way bigger than the money people make for getting in early.
