If that were true, doesn't it support my thesis even more— the distribution is abnormally inequitable and thus the coin's market cap can't rise to lofty levels.

I'm not really opposed to your views, but it should be said that the Bitcoin economy works perfectly well with only a small fraction of the coins in float.  It just doesn't matter what the price is.  Volatility is more important, but it is declining with increasing price, and there are work-arounds for it.  It is technically feasible to make volatility effectively irrelevant to transactional applications.   Much wealth depends on this, so it will become pervasive.

If you're saying that bitcoin can't become valuable because it is too scarce, then I definitely have to disagree. 
If you're saying that bitcoin can't become highly utile because it is too scarce, I also disagree because of infinite divisibility.
It would be a categorical error to blindly apply models developed and tested exclusively in an environment of finite divisibility to an environment of infinite divisibility.

How can you assert that a fit with one model is lesser fit than a fit with another model? Define 'lesser'?

The best fit is when you have a better R-squared value than any other fits. Excel calculates the best fits for every model automatically, so you can just conclude that a log-linear model has a better fit (0.94) than log-logistic (0.73).

If I am not mistaken, the best R-squared (least error from the data points) would be an N-degree polynomial for N data points such that the curve passes through every point.

Thus 'best fit' may have no correlation to predictive power.

Surely you of all people understand the concept of overfit, as it is deeply connected to ergodicity, which seems to be central to much of your thinking.
If you want a pragmatically useful and statistically rigorous treatment of overfit in predictive financial models, I suggest recent works of Marcos Lopez de Prado.
For my purposes trivial heuristics in the number of parameters are often more practical, since I need to do calculations for very large ensembles of diverse models,
but Lopez de Prado's stuff is on much firmer epistemic ground and very suitable to systems involving relatively small numbers of models (perhaps millions).

Quants always fail eventually because as Armstrong points out their data sets do not encompass the long-tail events from a plurality of completed case histories going back 1000s of years.

Everything fails eventually.  You can often generate a good distribution on that pretty trivially.  All the reliability models for quant models are quant models, ultimately.

As for long tails, that makes modeling harder, not impossible.  Harder is good because it means less competition.  (Bad because it takes longer.)
I have data back to Sumerian grain markets.  One of the wealthiest people in the world spent a lot of money collecting such data for my convenient use.  (He charges an arm & a leg for it.)
Data is too sparse to be of much use by my minimal confidence threshold before Alexander the Great.

Bitcoin is not just a new technology being adopted : It is fundamentally money, and the reflexive dynamics of profit apply. When you start looking at assets which trade in a profit pursuing environment, standard relationships and theories are not helpful (they are likely to be 'proven' wrong as soon as they are recognised)

That is precisely my point that Bitcoin is too investor-only centric, and not enough utility-adoption-centric.

What IS important is if the growth trend is slowing or not.
Agree. For example, it is reasonable to suggest that "pregnancy" is shorter for early adopters and longer for general population. Then it would be steep curve in the very beginning, then less and less steep later on. Something like this:

EDIT: It's real data Sad

This has probably already been mentioned at some point, but have you given any thought to 'the chasm' that is inevitably encountered during adoption of a disruptive technology?

This feature (unique to disruptive innovations, in contrast with sustaining innovations) occurs after the innovators and early adopters (who, in total, account for the first 16% of total adopters) and before the early majority jump in. It appears while the innovators and early adopters revel in the adoption of a change agent, the early majority are much more comfortable using existing tools/methods and hesitate before adopting something that requires a fundamental change to their current operations. This hesitation forms 'the chasm'.

Using 2.1 million as the value of current adoption (taken from My Wallet), and assuming we have reached the chasm, that puts the future total number of Bitcoin adopters at approximately 13 million. (Granted, this value does seem a little low, especially considering it is only 9% of PayPal's current users.)

Anyway, it would be interesting to hear your thoughts on this...
I don't know much about chasms. Usually new technology adoption is drawn just like smooth S-curve. Are there real-life adoption curves where the chasm is visible? Would be interesting to compare with our graphs.

Micropayments need to be off-chain until they reach a threshold which would be time or value based, then a summary transaction gets done on the blockchain.

Then you can't pay anyone from the same account. Sorry that doesn't scale the same.

Chasms are apparently a speculative investment phenomenon applicable to a company or market, not a decentralized adoption of technology, which rather tends to be a logistic S curve.

Don't forget that SatoshiDice started in April 2012 and kept growing until it was doing about 70% of the volume a year later. Each bet was a transaction pair in the blockchain, and some people were even using bots! Fee increases and SD internalization got rid of most of its volume by about July 2013. So the growth since then is much more of a "real world" business flow. Still, some spam-like volume coming from betting sites.
I can't see traces of this in the chart. Maybe because it's "excluding popular addresses"?

Yes, that's probably why that option is available.  Smiley

However, other business is missing, like btc purchases on Overstock from Coinbase account holders.

This is NOT decentralised though - problem is that we need micropayments in a networked economy and BTC is hostile for this.

One person's doggie poop is another veterinarian's GDP. Imo, when we start killing txs, we've lost the plot (of the internet paradigm).

The tx's weren't killed. They were internalized within SD, off-chain, how it should have been done at the start. GDP remained and SD was sold for 120,000 BTC.

Fair point, but I will counter that if there are real txs where parties can trade their balance with any other person in the universe, then off-chain is not the same jungle nor the same network effect.
Nailed it!

Did you ever calculate the market cap of bitcoin with a 2000 dollar value?
That would be a current market cap of 24 billion dollars.
Such a small market cap cannot sustain any real economic transaction value, where banks, businesses and consumers use bitcoin for all kinds of offline and online financial transactions.

The $2000 is probably too low. I think $3000 is nearly assured, and $5000 - $10,000 is somewhat likely.

$10,000 x 15 million coins in 2015 = $150 billion.

Here is some justification, but apparently the Bitcoin velocity of money abnormally low for a currency and thus won't reach Paypal's scale at least not on-chain (i.e. off chain fractional reserves and debt won't be limited to Bitcoin's money supply):

Hmm - do you say that the line you are watching is not 'USD/BTC = exp(-2.869800 + 0.003012 * D), D being the number of days' anymore? Have you changed the coefficients or have you changed it altogether so some other function?

It is always, every day, the line (or other construct) that gives the highest R^2 fit with the USD/BTC price data between 2009-1-3 and present_day. For all the time it has been an exponential function, which is linear when plotted in logarithmic space as I do.

Your comment about only one best fitting trendline only makes sense if you constrain your search space - for example by choosing only exponential functions.

A side note - if you for example allow for trendlines to be polynomials of unrestricted degree - then you'd be able to fit the trendline to the price chart exactly (with no divergencies at all).

1. Not really. Others just don't come close. 2. That's quite theoretical, since I cannot convince myself that a model with more than 2nd degree term is anything but noise with no predictive power, and Excel allows construction to 6th degree, with no improvement in R^2.

What IS important is if the growth trend is slowing or not. I currently hold the opinion that the trend is pretty much intact and price is about to increase 10x in a year. AnonyMint thinks it has slowed.


If we ever hit $5000/BTC... I give you legal ownership of my left kidney.

I like my kidneys... so what I am saying is that will never happen. Not next year. Not ever. Merry Christmas.

I could see $1500-$2000 in a bullish scenario.

Too many new players, too much regulatory bulls---, no Willy Bot, reduced black market presence, newbies getting Wall Street raped, etc., etc. Just because new adoption has, historically, been at a certain rate does not mean that this new adoption will continue out into the future. The baseline for the forecast is off.

It's, logically speaking, not terribly far off the rationale that banksters and credit agencies used in assigning inflated ratings to what were truly junk bonds -- the price of housing had not historically gone down and there had not been such a batch of foreclosures in prior history (and that sample size was much larger). However, the situation had changed... you had different people buying homes, different underwriting standards and down payment requirements, the perverse incentives created through securitization and derivatives, and balloon payments that functioned as a ticking time bomb.

Here, the dynamic that has changed is different, but the result is similar... adoption rates increased more dramatically when the price was still psychologically affordable. Now, simply having seen so many people profit, a lot of new users know that they are late to the game and that the odds are higher, now, that they'll be left holding a bag rather than profit. Tack on the fact that we went pop (moved away from black markets and towards regulation, taxation, and Wall Street) and have, resultantly, lost our hipness and appeal. Yea, this s--- is going down man. I'm not saying your math is wrong, but the application is off base.

Wait until more people start asking for wages in bitcoin... you are looking at sky high prices.  Unlike the merchants who currently accept BTC and convert instantly to $ employers would need a stock of BTC for pay day #1.  #2 Once employee is paid he rarely will spend all BTC instantly.
