But $240/$60 = 4, not 5 miners??
Or I am missing something?

Is it $60 fee per miner per week? Can you clarify?

I don't think "interpretion" is an English word 

Yes, there are many examples, but it is not seen as a problem (I don't really understand it either, like people are brainwashed into believing Bitcoin is anonymous; you are not paranoid). Immediately after I receive/send bitcoins from/to a person, it gets really complicated for me, because I do not want that person to track what I am doing with the money. There is about a million examples where you have something to hide from person who you are trading with (while not doing anything illegal or even immoral).

No payouts yet, probably WH just forgot to delete "Total Earned" cell for miner 5.

It is a transparent public ledger. Not even near anonymous, exact opposite of anonymous, especially if you trade/buy/sell personally with somebody you know.

KnC is shipping 550GH/s miners, almost 500 units per day. That equals to about 250TH/s daily!

According to order numbers, they sold close to 10000 units (order numbers below 7500 were supposed to be shipped by 15.Oct., I don't think many more people bought them, even whenprice dropped).

10000 * 550GH/s = 5.5 PH/s increase in about next 20 days

Did I get it right?

A Ponzi scheme is evil (it is a crime in fact). Fraction Reserve Banking is just a fancy name for a Ponzi scheme.

It is only useful if you have separate channel to verify the PIN/SAS (similar to Bluetooth pairing), like in the restaurant where you can visually verify it.

People untangled it, everything is transparent: banks have been fu**ing people all over the world. Just look at the LIBOR scandal - worlds largest banks addmited that they formed a cartel, somebody sued one of them, they managed somehow to convince the court that anti-monopoly laws don't apply to Banks!
BTW, system is not fragile due to its complexity.

For people seeking trustless key exchange algorithm: it has been already invented (i.e. you can avoid MITM attack without relying on PKI) - ZRTP could be easily adapted to bitcoin payments, changing SAS authentication string to PIN , for example, as it can be only 16 bit number. However, you would have to trust the merchant not to scam you. I don't see the problem with this in restaurant/bar scenario.

Soo, what happens if one EU country treats bitcoin like currency and another like commodity, gift card or whatever. I mean, the EU is a single VAT area (or something similar, meaning only  the rates are different)? Do I have to open a company in Sweden to do business in EU ( just using bitcoin for payments, not doing banking, exchanges or brokerage)?

It is not so simple, there are serious implications. After second deposit by company C the total balance in all of bank accounts is doubled! After the bank lends the money to D, there are now two persons with bank accounts with balance of 1 (BTC or USD, or whatever) and one person (D) with actual cash or coin. Now, suppose that person D burns the cash, dies and loan collateral is also destroyed or devalued. Then bank defaults and TWO persons are loosing their money from the bank (A and C). Thus, the economic effect is just as if the multiplication was real, not metaphorical, I.e. two persons are hurting because they lost a coin, even when there was only one real coin. This scenario on a large scale is the source of all economic problems today.
The core of the problem is lying to people on many levels. It starts by lying to average Joe that bank is just "keeping his money", not lending it again. There are lies for people who ask one question, then lies for people asking next question, then more lies. But if you ask too many questions, you eventually come to truth, and what was conspiracy theory a couple years ago today is known fact.

Presumably, another use case would be "find the most expensive place to sell bitcoins"?

AFAIK, when sending USD to btc-e you must pay a high transactio fee.

You can take the cash. But the more cash you hold, more value you loose by not earning any interest. So eventually cash finds its way back to to the banks, and cycle starts again.

In order to have fractional reserve banking people must save money in bank accounts. To make people do that you must make their money worth less and less by printing more and more. So people are happy to be able to save money, with interest rate a little below inflation.  No inflation - no need to save bitcoins in a bank (unless the bank is paying you interest above inflation, loosing money, or convince people somehow to give them their money).

The question here is about human nature. One must be careful when reasoning about it, because all people are not the same (like oneself, for example):
- "all people think like me, and I would (not) work, so the system would be great (not)"
- or "I work exclusively for money, thus nobody works for fun or any other motive"
- or "I would not work as a janitor, so nobody would"

Nobody even considers other possibilities to get something done; that is maybe there would be no janitors in Switzerland: even if there is no official janitor in some facility, maybe people would do simple janitorial work themselves. Or not, who knows. The point is it is better to try change the system BEFORE the system destroys itself.

Humans regulate bitcoin too.
Or maybe we already reached singularity (Skynet posting messages to internet forums  )

Just look at this mining operating margin chart http://blockchain.info/charts/miners-operating-profit-margin (clearly, the chart is invalid for KnC, but they only have like 20% of the total power, and the chart is probably valid for old miners)

Yes, but we are talking about just a couple of weeks here. The only significant event related to bitcoin is KnC shipping in last two weeks. It is the simplest solution.
