If there is really a fork with unlimited transaction size, then most will follow it without questioning, people are ignorant, as long as their coins are valid

Actually as a business owner, he might be very willing to take customer payment in BTC's form, so he can do whatever he want with those BTCs and they will never appear in the tax declaration  

There are so many chinese business owner who have plenty of fiat money at hand without any good investment target

No, by that time, there is no other currency, no exchange rate

Given this view, the BTC price will eventually equal to the electricity cost for each miner in average, given 3600 miner and average 1 BTC per miner per day, if the price really reached 200$, that means each miner will be able to put in 1000Kwh electricity to mine 1 BTC per day, that is crazy, heavy pollution

I think like this:

First year, there are only 7200 miners, they divide 7200BTC per day, average 1 BTC per miner per day

Second year, there are now 14400 miners and they divide 3600 BTC perday, average 0.25BTC per miner per day

But the price increased by 4X and every miner still get the same amount of return in USD's form, the price increase keep the mining operation profitable, since they have to pay the electricity

Now, the ASIC arrived, there are still 14000 miners divide 3600 BTC per day, but some of the miners have upgraded to ASIC, and some of the miners will quit the game, so generally I think the number of miners will decrease and their share of BTC per day will increase （because ASIC supply is much more limited comparing with GPU supply before)

But on the power usage side, if the BTC price rise very high, then the power usage will rise accordingly, so ecological or not, purely depend on the BTC price, if the price is high, then the consumption of energy will be high, it has nothing to do with the technology used for mining

Highly agreed, I also think all the changes could be done at higher level without modifying the original protocal, to keep the integrity of the blockchain

I never said I will force a change, I mean if we need to consider a hard fork or not, take block size for example, some people do not like big block, some others think that is a necessary for future success of BTC, how do you solve that conflict?

See the other discussion about block size:
https://bitcointalk.org/index.php?topic=140233.0

You can not always avoid the problem with technology, the decision making is unavoidable for everyone, either follow or not follow a new fork. If that fork is coming from very authoritive guys like core developers, there will be conflicts, maybe half of the people stay with original protocal and the other half go for the new protocal, then...

I had a feeling that this will become a question sooner or later, either we stick to the original protocal, or we have a mechanism to solve the conflict in opinion

I personally hate politics, during my working years at super multinational corporation, it is always political change that made people feel unsafe and uncertain, and that always changed the product consistency

But the world will always change in an unexpected way, so the ability to be able to change might be needed for survival. Every change could also lead to ruin, so who have the right to decide this change? And who can be responsible for the result of the change if it turns out to be a disaster?

If we really need to do the change, it should be very well understood, tested by the mass and it never change the consistency of BTC itself

Let's say that there are couple of semiconductor manufactures, they accept BTC payment, then they need to use BTC to pay salary for employee and other costs, unless all that cost can be paied in BTC, some exchange is needed

But, they could have a deep saving account in local currency, so they just accumulate BTC in the process, while use the local currency saving to pay for the costs, this could be considered a benefit if the BTC price rise continuously, but then Avalon ASIC sale in BTC ensured this will happen

There are many levels of this kind of self improving feed back, as long as the price is rising

I guess many of their high end GPU were bought to mine coins. This day is not far away if BTC price rise enough high, making ASIC devices are much eaiser than graphic cards, they need only a small project setup, and their 32nm process is already mature

I just wonder when will AMD join the game...  Their stock performance is miserable, this might be the chance to turn the tide for the company, they could easily produce the most advanced ASIC devices using their 40nm process and very mature cooling solution, then we will back to the old gpu mining era 

As long as Ben do not tighten, exchange price will rise

No, if BTC price rise to enough high, then you can consider spending some of them

You spend money because of:

1. The value of that money is dropping because of inflation
2. You have enough of that money
3. You have constant income of that money

1  is not valid for BTC
2. might be valid when BTC price rose to enough high
3. Even if you are a large scale miner and you mine a couple of coins per day (only  3600 per day in total) , you will only be able to spend couple of coins per day at maximum

Last year, I have pointed out that if some very hot electronic product (for example iphone5) only accpet BTC purchase, then it will push the price up and act as an accelerator for the BTC economy

Now something interesting happened: Avalon ASICs second batch only accept BTC payment

This is a self generated demand, for almost 1 million dollar. This will push the price up and the effect is already shown on the mtgox price

And the question is: What will happen then? There are many variables, but will it result in a self-accelerated loop or just cool down when Avalon dump their BTC payment to buy semiconductor components?

BTC is scarce, the supply is constantly decrease, if someone sold a huge amount of BTC, he will very likely to buy it back at a much higher price level, and it is not a guarantee he can get that same amount of BTC without pushing price much higher, so basically it is difficult for investors to act on the short side

Other things like gold/oil/house, the supply can always increase with added production capacity, so the price development is much more uncertain

It's driven by speculation, any serious speculator will never miss this vehicle, this is just the beginning

5 hedge funds, each push the price to a target area (like 4x) and dump it to the next one, they keep buying and selling with profit, same game wallstreet guys have been playing for decades

Actually I think the biggest enemy of BTC are these players with huge amount of fiat capital, although BTC was designed to be a currency free of central banks manipulation, it still could be manipulated by the powerfull players in the market

One Bitcoin can be compared with one ounce gold coin, so we could use 1/2, 1/4, 1/10 BTC etc...

Below that, there are other weight unit, like carat (bitcarat) and grain (bitgrain)

I suggest that one carat bitcoin (bitcarat) = 1/1000 bitcoin, this sounds luxury enough

And one grain bitcoin (bitgrain) = 100 satoshi = 1/1,000,000 bitcoin

I believe it is not a scam, but there are much more besides a working product, I think BFL feels like a well established business, while avalon feels the opposite, especially the custom service

Then it might have a touchscreen 

Bigger than a mini pc case, how could it automatically connect to your wifi without any user interface to input the wifi password?
