We’ll sign off with the simple point that unless a massive amount of new capital is transferred into Bitcoin market sharpish — which is not impossible, since there are still a number of deep pocketed believers out there — it’s hard to imagine the asset class going any other way but south.

Right now, Bitcoin is only mostly dead. As an investment, it was the worst of 2014. . . . The problem, though, is that Bitcoin will likely not survive to get to that level of innovation. Will Bitcoin enthusiasts support it after they realize it has ceased to be useful as a currency and is a terrible investment? Not likely. At some point they are going to realize that they are subsidizing Bitcoin for theoretical and emotional reasons so that it can be exploited by regulation-seeking venture capitalists. When that happens Bitcoin will shift from being mostly dead to being all dead.

Bitcoin is not [the future]. It is a step along the way and will eventually disintegrate. . . . As a currency [Bitcoin] is almost negligible against anything. It can't stand toe-to-toe with the Cuban Peso. . . . With Bitcoin the pretend currency, what you see is not what you get.

We need to consider the distinct possibility that Bitcoin is dying. A star gone supernova. Something will be there for a while, but it will never be what it could have been. . . .

Neither Satoshi Nakamoto nor Bitcoin ever stood any chance of operating outside the bounds of conventional society. There will be regulation, there will be consumer protection, there will be rules and taxes, and criminal prosecutions for those who break the law. Bitcoin isn’t cyberpunk fantasy and it isn’t a Thomas Pynchon novel. It’s dull. The thrill is gone. And that’s why people are so mad.
