yes it's right, chinese win on the ultra low cost of electricity because they use coal,even some people call it a clean power source even i don't sure because of its polution,but they also give an advantages to make bitcoin transaction go faster

China also makes most of the ASIC miners, which are paid for in BTC.
Which means there are some Chinese manufacturing companies who hold a ton of Bitcoin.
It would be great to see some competition in the ASIC market, but just like with most things, most people will not be able to match the production costs of making the chips in China.
Labor and electricity is so cheap, regulations are not strict, etc.
China is the perfect place for anything related to Bitcoins, so they naturally have an advantage.

Yes, I believe that bitcoin is not controlled by anyone no matter how large their stocks or how many and powerful their mining farms are.

The only thing they can influence is the price of bitcoin in the market. With huge amount of stocks at their disposal it is of certainty that their actions will play a large significant impact on bitcoins buy and sell.

agree with you, the goverment not make difficult regulation to build "mining company" also goverment support digital coin, i read a news some week ago about official cryptocoin of chinese, maybe in future we will see chinese will accept bitcoin as regular currency.

China has big part in bitcoin community too since they are the one that hold most of the coin(thru mining) they can also manage to control it if they want. What they just need is a team work for each other.

you're right, I think china having an enormous mining for bitcoin, so they might be able to manipulate the price if they want to, but I guess it would not do, because most likely the income they get comes from bitcoin. but perhaps there had a very great mining and technology is good enough for bitcoin. because I heard that China is a country that has a large population, so many of them are unemployed, maybe with this they can make money with a good deal

I don't think China is controling Bitcoin.  They may have the majority of the mining farm but some of them are  owned by foreign Capitalist.  It was established there because of cost efficiency perhaps.  So having Chinese as the mining farm worker doesnt mean that they control Bitcoin.

China does not control bitcoin. However, they do have the capability to manipulate the value of bitcoin since just as you said, they have huge mining farms and most of the percentage of coins are held by Chinese bitcoin users so they have the upper hand in terms of volume.

In moment of my voting score is 61 v 61. I voted for no, cause I still believe that bit coin is decentralized. maybe there is a lot Chinese useres, miners but that doesn't mean they own entire network and bitcoin.
Probably they have good conditions for mining, low cost electricity, cheap mining equipment.
I hope nobody will ever control bitcoin, but that will be hard to achieve. To many hungry sharks out there.

China being a major player in Bitcoin doesn't mean other countries are not of importance. So yes, Japan and Russia are also contributing heavily when it comes to number of users etc. Nice thing is that while the Russian government is treating Bitcoin as the enemy, the Russian citizens seem to be going nuts on Bitcoin and everything related to it. Every one loves Bitcoin.
