But hey, let's talk about Bitcoin? Why not! It's super interesting. I think there is not enough real debate about it on HN!
I think we are facing a massive wave of change due to the crypto technology that is currently developed. I expect it will be as big or bigger then the internet. But I am skeptical about Bitcoins share in the long run. I doubt we really need the mining. I expect that there will be new technologies that enable crypto without proof of work. And they will become strong competition to Bitcoin.
However, the market is so enormous that even with a small market share, Bitcoin could be worth the $100B it is currently traded for.
