From Wikipedia: "An economic bubble or asset bubble (sometimes also referred to as a speculative bubble, a market bubble, a price bubble, a financial bubble, a speculative mania, or a balloon) is trade in an asset at a price or price range that strongly exceeds the asset's intrinsic value." Seems like a reasonable description of bitcoin to me I have yet to see a well thought out, rational, specific description of the intrinsic value of bitcoin. If it is the case that people think it will either be zero or a trillion market cap, that suggests to me that people aren't thinking seriously about the real world end game for bitcoin and thus that there's is no solid bounding of the potential intrinsic value Bubbles are formed by people who think they are being rational, but in fact are not. One sign that you aren't being rational is when you don't think critically, quantitiavely, specifically and probabalistically about possible future states

Is Gold in a bubble right now? Because the current price of Gold strongly exceeds the intrinsic value of the material and it has been like that for a while. Bitcoin has pivoted away from being a currency. Bitcoin is now a store of value, like gold.

  gold has always been a weird instrument since it was decoupled from fiat currency, and it has a unique position because it has been around for a long time so investors sort of understand it. the value of gold is determined a lot by confidence in the asset's performance as a "non correlated" backup medium of exchange. there is a long track record here, which matters, despite how "soft" and "squishy" this line of thinking may seem to someone who doesnt work in markets. bitcoin doesnt have this: it is not widely used as a store of value, and it does not have a track record. basically, the perceived probability of it going to zero is infinitely higher than the perceived probability of gold going to zero this article does a much better job than i just did: http://www.businessinsider.com/economist-jim-rickards-bitcoin-versus-gold-price-manipulation-2017-12 http://www.businessinsider.com/economist-jim-rickards-bitcoi... and heres an intersting history of gold: https://www.investopedia.com/articles/investing/071114/why-gold-has-always-had-value.asp https://www.investopedia.com/articles/investing/071114/why-g...

The optimistic scenario is that Bitcoin becomes a currency like cash or a store of value like gold, in which case it will be valued in the trillions. Somewhat conservatively let's say that the market cap in these scenarios is $2 trillion USD. At today's ~200B market cap, this implies the market is giving 10 to 1 odds that bitcoin is going to zero. Not sure how any of this is on its face "irrational".

  the irrational part is 1) an overestimation of the likelihood of bitcoin becoming worth $2 trillion in a reasonable timeframe (1 in 10 odds of that happening!?) and 2) underweighting the value of large changes in low probability levels: based on the above back of the envelope math, you ascribe 10 to 1 odds of bitcoin failing. the math that supports that is so imprecise as to be almost nonexistent, but the details are important: if the odds of it succeeding were 1%, or 0.1%, would you still invest? what evidence do you have that this number should be 10 to 1 rather than one of the above? have you given any thought to this, or to what probability of failure would make you get out of bitcoin? have you thought through the likelihood that one of the binary scenarios you describe doesnt actually happen, but in fact that a gray area wins out: for example, bitcoin may continue to exist as it does now, as a fringe speculative asset class with vaguely defined but high potential. it may stabilize into the go-to currency for money laundering, funding illegal activities, etc. it may serve as a stable currency for a subset of the digital economy that just likes the libertarian appeal of bitcoin. if you look at where bitcoin is now, and try to draw a straight line to the future, it seems to me that youd intersect one of these scenarios rather. if you havent thought these things through, but still invest, you are being irrational edit: maths

    If the odds of success are anything less than .1, then buying at the current price is a bad idea. I agree with you that the odds are in fact less than .1 but it's just a guess - if somebody else thinks it's .5, well, who am I to say that they're wrong. Pretty much any investment thesis involves guesswork at some point. That doesn't make investing irrational.
