when i use google which this word "bitcoin price usd" find price and when use other exchange site price change

Because the price of each bitcoin in those exchanges varies because of the volume that each one of them have at the moment.
If as an example, poloniex is having a lot of volume and suddenly btc drops to $7700 while bittrex is selling those bitcoins at $7850, you can make profit by this just by withdrawing those coins, depositing on bittrex, and selling for tether, and doing the same scenario once and once again.
It is not difficult, it is called arbitrage and it can be done in a lot of exchanges because there is a lot of difference in a lot of them. It is just another tip if you want to make an easy money, obviously that it is a little bit more difficult than trading.

if you are checking the price on sites that are just reporting it (in other words they are not exchanges) then they are reporting an average price. for example bitcoinwisdom.com first page, bitcoinaverage, coinmarketcap. even preev.com unless you specifically change the view to specific exchange price. and average can be different from the real price specially since some of these places like coinmarketcap update the prices with delay (5 min in this case).

but if you check the exchanges themselves, or the live price so to speak, it should be the same everywhere with a very small difference (less than 1% most of the times). and if it were bigger like a 10% difference between price in two difference exchanges and if it stayed that way, that means that exchange has some issue that is causing the difference because if it was a normal exchange with no problem the price would have changed to be at equilibrium with the rest of the market.

So if i have huge amount of bitcoin like 1000 BTC can open site and set price like i want ??

no, because it is only easy in theory.
in practice you are going against the whole market. the trading volume of bitcoin in past 24 hours has been about 550,000BTC, your 1000BTC will be lost in that sea.
also you have to do it consistently which means every second, every day to do something to control the price specially if you are going against the market like dumping for example. a one time thing won't work.
that is why manipulating the market is becoming harder and harder as it becomes bigger.

Its not very easy because now bitcoin is very big market and your 1000 bitcoins can lost very cheaply and quickly if you going to against market current volume is going over half million bitcoins per day so you can imagine what happen to you in sea when whales coming

If you have many $ in a exchange and this exchange havent enough BTC the price is higher

There is nothing unusual. When you shop or choose a product on the Internet prices for the same product can have quite significant differences. The same is happening with bitcoin. If you are an experienced trader then you can successfully to use it to increase their profits.

Also the transaction fee's are different on exchange sites. There can be a fee if you transfer (crypto-) currency from or to the exchange. There also may be limits on the amount you may deposit or withdraw.
You need to check the complete process.

The price of bitcoin is different not only on sites, but even in every transaction. Since it is determined only by market participants.

coinmarketcap gives you the average price of the bitcoin from whole of the bitcoin markets. another just like bitcoinwisdom just give you the rate from some major exchange sites of the bitcoin.
Every exchange site has own volume and demand. Remember about the bitcoin prices depends on the demand and then it meets the interest

It's good to go through coinmarketcap and find the perfect price for bitcoin. Different exchanges quote different market value based on the circulation happening through respective exchange. Some traders do arbitrage trading using few of the exchanges and get benefited through the same.

When you use google it is generally showing the price quoted by coinmarketcap or coingecko. Which is the average price of every token from all the top exchanges. It varies from exchange to exchange because of different demands and supplies over different exchanges. Moreover the amount of altcoins listed on that exchange. For example if an exchange has more altcoins. People want to buy altcoin by selling btc. They would be willing to sell btc at a lower price too. This is applicable vice versa too.

I can sure said the same things involving google and currency I have been using google site when checking for the price of bitcoin and I think it is accurate for me, you can sure see different price from different exchange site, and because of the supply and demand for such things but I think the price on google and such different sites varies from different time interval that is my theory on how bitcoin price change from site to site.

In general, even for bread in different shops, the price is different. In my country at least.

every people instantly surf about the bitcoin price in the Google search itself.
But if there is involved in transaction or trade means you have to go with the preev or Coindesk chart.
Since the updation time and people dynamically managing it, you will find the bitcoin price as the same value after some time. If there is no volatility in the value you can find the exact same value in the every price index site.

Well yes but you're not necessarily getting the same bread whereas bitcoin you are getting the same exact thing. Though like bread there are also differing costs to consider that are incorporated in to the price, some exchanges charge higher fees etc. Then as mentioned there are different markets on each exchange.

Individuals place buy and sell orders so the price is going to be whatever the last completed transaction was. It’s never going to be exactly the same on every exchange, but it shouldn’t be a big difference. If an exchange is only available to one country or if it limits certain countries, then it will skew the price. Or if the trading volume is low on a particular exchange, this could make the price different than other exchanges. Otherwise the differences between exchanges should be minimal.
