I thought this was a pretty good article, particularly the bit comparing it to gold:
" Crypto-evangelists often cite gold as a similar asset class, in that it has no value beyond marginal industrial uses; its value is what people say it is. Maybe that’s a good comparison, but I’d apply it differently, by noting that the base value of gold is not just in those industrial uses, but also in the hundreds of millions of people around the world who believe that it looks good or can bestow prestige. Granted, this is a historical/cultural value, yet it’s proven pretty reliable over the past, oh, 5,000 years or so. And it comprises at least part of the price of gold, one that should persist no matter how other factors fare.
In that sense, Bitcoin has a similar base value, but it lies not in history but ideology: namely, the belief among evangelists that the world is in need of a medium of exchange backed only by computation and free from the oversight and manipulations of governments and corporations.
How many Bitcoin investors today hold to that ideal is an open question, but I think it’s safe to assume that the recent speculative bubble has not been fuelled by a mass conversion to libertarianism. If that’s right, then the base or “intrinsic” value of Bitcoin, supported by true believers, is somewhere under US$1,000 — where it was a year ago. (That’s assuming, of course, that the believers’ faith is more or less unshakeable; we’ll see what happens if the meltdown continues.)
Everything else (about US$10,000 this week) is the speculator’s share of price and has proven itself to be remarkably volatile — which is to say, hardly a good store of value. The gold price, which has seen annual moves in double-digit percentages before, is capricious enough, but it can’t hold a candle to Bitcoin.
The other problem is probably bigger: as a currency, Bitcoin sucks.."
