There is a short document somewhere in the NYSE site that describes the their bitcoin price index. It is some kind of day average, computed (by a secret formula) from data provided by an extensive list of bitcoin exchanges whose names begin with "Coin", end with "base", and are at most 8 letters long.
The price is updated daily at 16:00:00 UTC (4 pm London time), weekdays only.
It seems very useful, for what I cannot say.

When all costs are considered, electricity from an on-board battery is a lot more expensive than electricity from a wall outlet, and absurdly more valuable for the owner of the device. Therefore, placing miners on mobile devices like smarthphones, tablets, or laptops makes no economic sense.
Moreover, I cannot imagine any advantage of phsically attaching a mining device to some other device with a different function, except water or space heating. There is a thing called "internet" that allows a device to send information to another device anywhere in the world; and a system called "bitcoin" that is supposed to allow bitcoins to be sent through the internet, even if the two parties are not connected to the internet at the same time.
So, instead of having 10 mining chips scattered around, firmly attached to my devices, I could have one mining rig with 10 chips sitting anywhere it is more convenient (for example, in my water heater, or in the attic of my summer home in Iceland), sending bitcoins to other devices if, where, and when needed. The centralized rig would certainly be more efficient, could work at steady pace 24/7, use optimized power supply -- and would not burden the other devices with power load, extra heating, board space, etc.. Physically attaching a mining chip to a router makes as much practical and economic sense as attaching a water filter to a toaster, or a lawn mower to a car.
I cannot make sense either of the fuzzy idea that, with miner chips, devices would be able to get revenue to do micropayments for the services they use, or to generate satoshis for "Wide World Ledger" applications like colored coins, authentication, timesamping, etc. It will be impossible to exactly match the bitcoins produced by a device to its needs: if the device does not run out of bitcoins, it will generate a surplus of them. My water heater could generate a lot more bitcoins than my laptop, but will hardly need them; whereas my laptop wil probably will need them the most.
So, if my devices had embedded miners, they would have to pool their bitcoin streams and share them on the basis of need; and possibly topped up with purchased bitcins. Which, again, is better done with a centralized mining rig than with independent miners. (By the way, in most higher organisms, from corporations to computers to humans, evolution has found it better to use specialized units for the generation of "revenue" (money or energy), separate from units devoted to other functions that spend from that "revenue".)
Finally, adding a mining chip to a battery charger makes it much more complicated, functionally. Instead of just taking AC 120 V and putting out DC 6 V, a "miner-enhanced" charger will have to communicate with 21.co servers, manage a wallet, interact with other devices, authenticate itself, etc.. Even if most of that complexity is hidden from the owner, enough of it will be exposed to require some of his attention and time. Which are much more expensive than the electricity or the chip itself...

The more interesting thing was the 0.22 w/GH 22nm chip, 2.5 times more efficient than the latest generation miners. If they already have that and are running them they're making good profit.
Is it known how many GH/s does that chip put out? Any guesses about the size and manufacturing cost of the chip?

On the new NYSE Bitcoin Price index: https://www.nyse.com/publicdocs/nyse/indices/NYSE_Bitcoin_Index_Methodology.pdfThere is currently (1) Exchange/Venue whose bitcoin transaction data is included in the calculation of the Index:
* Coinbase Exchange https://exchange.coinbase.com/
[ ... ]
The NYSE Bitcoin Index will be calculated utilizing a proprietary, rules-based formula that is maintained and overseen internally by the NYSE Index Committee [ and reviewed and updated quarterly ]. The logic utilized for the derivation of the daily index level is intended to analyze a large amount of actual Bitcoin transactional data, verify and refine the data set, and yield an objective, fair-market value of (1) bitcoin as of 4 PM U.K. time each weekday, priced in U.S. Dollars (USD)
Well, this will surely stabilize the bitcoin price. No more wild swings of 50 or 100 dollars within a day, or the traditional weekend dumps and rallies. I suppose that all of you will henceforth use this price index to guide your trading, instead of those silly real-time charts.

Stolfi, I was asking for the "Major Bitcoin News website" that confused one European nation with another. Sounds vague and made up to me. But I guess it doesnt matter now.
http://bravenewcoin.com/news/xapo-moves-headquarters-to-switzerland/Switzerland has long been known as place that respects financial privacy, but that may not be true for Bitcoin companies who reside in the country. BTCX, a Swedish Bitcoin exchange, said in March that local tax authorities requested extremely “intrusive” data of 20,000 customers. ... said BTCX CEO Christian Ander at the time to a local media outlet, DN.se. “We are wondering if this situation is exactly what the Swedish Tax Authority is looking for, or if they do not know what [ ... ]
EDIT: As a redditor observed, Sweden is not Switzerland, just as USA is not USB.

I bet that the old ladies in China who define the price of bitcoin have never heard of either.
Heh, that actually got a chuckle out of me. You gonna show us that article, or is it another "me telling you so is proof" shit you usually go with when asked to demonstrate something? I already posted many times this article, that describes the typical Chinese traders and investors who caused the Nov/2013 rally: Christian Science Monitor 2013-12-06 Why the Chinese can't get enough of Bitcoin - despite bank banhttp://www.csmonitor.com/World/Asia-Pacific/2013/1206/Why-the-Chinese-can-t-get-enough-of-Bitcoin-despite-bank-banEvery trader should be aware of that information. Understandably, it is never mentioned by the bitcoin "news" media or the Antonopouloses, Winklegosses, Andreessens, Sielberts, etc.. Do I need to explain why? A briefer but more specific description of those traders and investors is in that talk by Huobi's Wendy Wang that I posted earlier, around the 00:14:00 mark. Later in that talk she gives some interesting gossip about the mining situation in China and the mining pool that they manage (Discus Fish, IIRC).

I read the other day an article in a major bitcoin newssite that confused Sweden with Switzerland. But at least the reporter knew that they are countries, or a country, whatever. I bet that the old ladies in China who define the price of bitcoin have never heard of either.
