> Given that bitcoin isn't a medium of transaction anymore and a store of value
Due to that, I think Bitcoin has failed and I no longer see it surviving long-term, simply due to the fact that there is much better tech out there now in the form of "alt" coins. (Not going to shill any specific coin here.)
What do I mean by "failed"? I got the impression from what I've read from Satoshi that they wanted Bitcoin to be a type of electronic cash and not necessarily only a store of value (see e.g. [0]). Yes, decentralized and trust-less, but still useable for even micro-transactions (from the linked article):

Bitcoin seems very much inspired by Bit gold [1], which summarizes with:
> In summary, all money mankind has ever used has been insecure in one way or another. This insecurity has been manifested in a wide variety of ways, from counterfeiting to theft, but the most pernicious of which has probably been inflation. Bit gold may provide us with a money of unprecedented security from these dangers.
A currency (read: gold) only has value because we, as a society, decide that it does. Gold is a "good" store of value because we have currency depreciation with fiat, so storing your long-term value it in doesn't make sense. What happens when (not if) we stop storing our value in physical things like gold and we create a global digital currency that's fast, secure, trust-less, decentralized, and most of all a stable store of value? (Open to hear discussion on if that is even possible.)
A cryptocurrency with those characteristics has all the benefits of gold, without the need for carrying all that expensive-to-move, heavy metal around with you to be able to exchange any of it for goods. And you could exchange on a global scale, something not possible with gold. Banks would be on their way out, because the people would be in control of their own money.
What happens to government-backed fiat when people can exchange their gold like they would fiat? I'd think fiat would start to lose favor. But I'm not sure what affect that would have on world governments and society. (Again, open to discussion because I'm not super well-versed in these subjects.)
Currently, Bitcoin can't do that in its current form—that is, be easily exchangeable for goods—its simply turned into a digitized gold that has the same issues when it comes to exchange—but I think we'll eventually get there with a coin, and there's some promising altcoins that have awesome tech right now. Maybe that coin ends up being Bitcoin after all. Maybe there will be coins, plural, who knows.
Maybe all that is a bit too utopian and it simply can't work on a global scale with governments. Still interesting to think about.
