Marc Andreessen on Bitcoin

Bitcoin is still working today, exactly the same as it worked last year and the year before that and the year before that. By all the noise and all of the stuff and all of the crashes and this and that and the other thing, it just continues to work. It just is. It’s becoming like air or water. It just is, like it or hate it. It just is.

Bitcoin may or may not work—and frankly I don't think anybody knows one way or another. But if it does work, it could be profound and revolutionary and gigantic.

So you discount risk and return in that way. I'm completely excited to take that risk and it's a classic venture capital risk to take.

If something is to displace Bitcoin now, it will have to have sizable improvements and it will have to happen quickly. Otherwise, this network effect will carry Bitcoin to dominance.
