Which site has the most accurate USDBTC pricing? I need for Bitmex margin trading, thanks in advance.

You can go to Bittrex or Poloniex. There you can view prices and easy buy sell Atlcoin. If you are a trader, the Bittrex and the Polo will be the 2 best sites where you can select.

you can not believe it in 1 source,you need to find it in different place and find the different between one and another.
usually i always use bitcoinwisdom.com and https://cryptowat.ch/ to monitoring the price,
but sometimes i used tradingview to see it in there,
you can find the difference between one and another,but if you do that you can minimize the errors,
i believe there are not the 'most' accurate one because sometimes you will see an errors

try to visit this website https://cryptowat.ch you will find live trading more accurate if your pc's specs are good and your internet connection is fast for nothing.

you should get bitcoin price from the same place you are trying to trade in!
if it is Bitmex then use Bitmex not some place else. the Bitmex price will be accurate for you. they are calling it XBT instead of BTC but it is the same thing. you can use their website or their API to fetch the price live from their exchange.

There is none. It will differ on where you are doing the transaction.
Most of the users here in the loaning industry or for exchange from BTC to USD use the preev website.
I dont why but I guess it is because this website updates the price more faster than any and it is easy to load even if you have internet connection problem.

Doesn't work out that way, because price movements are from all over for futures.

I think you trade Bitcoins on Bitmex so you need to track Bitcoin prices there. Because each place like Bitrrex, Poloniex or Bitmex, ... will be more or less price difference depending on the time.

I would recommend using preev to track the price of BTC as it takes the average price of a couple of renowned exchanges and you can expect it to be pretty accurate. You can even keep an eye on the tab opened on your browser, it would show you the price right there without actually having to move to the tab which is a great feature of preev and actively see the ups and dips.

For trading will be good to use our service http://strymex.com. We have a real-time price for Bitcoin and around 900 other coins. BTC price is aggregated from some exchanges. Soon we add some new features where you can choose the exchange you want.

The most accurate live bitcoin exchange rate can be seen at preev.com
They gather price updates from bitfinex,bitfinex,btc-e and localbitcoins to show highest market price at one place.
You do not need to refresh page periodically,just stay online and the website keeps refreshing in backgroud ecery five seconds.

Well i am not using other tools in terms of most accurate but i think this one can help you to know update price of bitcoin in different major exchanges with some other info like percentage of up or down today week or month.
You can check it here http://bitcoinwisdom.com

The other good thing here you can use some tools like you can put a line and analyse the movement of the price and any good tools and its 100% free..

I use Bittrex, but in the past Poloniex and Kraken did the job

Actually i use investing.com where i have already created portfolio of my trading products and i can easily see the BTC/USD prices over there its ok to use, but for accurate reading you can go with Bitcoinwisdom.com they are best one to use as they provide multiple exchanges prices and also with past 30 days price movement. Mostly there are slippage on every website during some big event when there is some big movement is expected, so you cant always aim for most accurate one.

There isn't really such a thing as an 'accurate' price because the price is different everywhere and isn't set by anyone other than the individual sellers. Personally I just use the bittrex price and that is good enough for me.

I don't think there is one site that is considered most accurate since Bitcoin doesn't have an official price. The best advice might be to look at a major exchange that has good trade volume. If the trading volume is pretty high then Bitcoin shouldn't have any abnormalities in price and should be about the same price as all other major exchanges. Some of the major ones are Bittrex, Bitfinex, Kraken, and Poloniex. You could also look a the price at Coinbase but they may inflate their price for profit since their exchange is a little different.

www.Preev.com looks great they manage to make an estimated by using Bitfinex, Bitstamp,Local Bitcoins and the now closed BTC-E.

As others have said, the most accurate price is the price you're buying and selling on.  Exchanges are different because the supply and demand ratio is different; different people, different volume, and different prices.

psti will be a lot of answers here, everyone has their own trust. so do I, always monitor the BTC / USD price movement at https://bitcoinwisdom.com/markets/bitfinex/btcusd and I always believe that it is accurate.  ;)

Just stick to the rate on the platform you are trading on. You cannot get a direct answer to that question you asked. The most important thing is that you make the best use of the platform you are on. Moreover, if you are going to be doing your trading anyway, it isn't like the platform is going to use another platform's exchange rate but its own. It is left for you to find the best platform that works for your own style of trading.

The platform where you perform your trading is the only important one actually. For the other prices, you can check with coinmarketcap web site and see the other prices easily.

There is no official bitcoin exchange,  so I can not determine which price of btc is the most accurate one. It also a problem to pay the tax of bitcoin profit or transaction.

A BIG THANK YOU FOR ALL YOUR HELP GUYS!
def. upped my futures trading game this past week after learning from you!

 ;D

I am also interested in your problem. Almost every time I buy USDT directly with my friend. The price of n is $ 1.3 / 1USD.

This will be my suggestion for your question !

In my own opinion and experience I think i'll choose two site and that is bittrex and poloniex..

this two site has the larger amount of traders .. and also has largest amount of  volume of market ..
for marging trading bittrex is the best for that but the difference between poloniex and bittrex is

the transaction fee .. Bittrex is the most expensive transaction fee than poloniex..

when we google it it dhows real time price, almost all wallets did too. But in terms in exchanges both poloniex ang bittrex works really well on showing latest price in real time.

It is not a matter of accuracy. All the exchanges have a price that is derived from their trades. An overall average, that is a tougher thing to find, I know that preev is there when you want a quick number and I don't recall ever thinking to myself that it was off by any degree.
It is easy and quick to load and works on any browser. I worry mainly about the prices on the exchange where my coins are. Shifting them around is a fools errand.

Every tradings platform sites have different usdbtc coin value that derived from its trades.there is minimum and maximum in terms of bitcoin pricing integrity.but mostly  bitcoiner used this two trading sites  bittrex and poloniex because its has an  85% of accuracy in USDBTC price and  mostly bittrex much  higher transaction fee rather than poloniex.
