Hi

aim wondering which source is used at coinmarketcap.

since they have no own exchange they need to receive a data stream from somewhere.

Most of the times the rates especially for BTC is the highest I could find somewhere.

thanks

Coinmarketcap is always using an average price (promedium) between all the exchanges that have bitcoin listed on their platforms.


And no, gdax is probably the only exchange that has bitcoin over $800 - $1000 of the actual price.

The same happens with BitHumb, when there is too much volatility, the price between it and the other exchanges  are far more than 10 or 12 percent.

Coinmarketcap averages out of all exchanges listed. Some of the data is delayed or possibly manipulated. Also into account comes in the circulated supplies + total. Other lists are usually missing one, so even though the rates may be higher through them, at least the market caps are usually a little better.

I've found that Google's rate is sometimes higher than the Coinmarketcap rate (now is a poor example, as at the time of this post it's only 1 dollar higher).

Personally, I've found Coinmarketcap to be a reliable source of statistics and while I do doubt their integrity because of all the Ponzi scheme related ads that they run, I don't doubt their ability to continue giving accurate statistics.

If you really don't trust them, you could try calculating the mean average price from all of the exchanges individually, but that could take a long time, during which the price could fluctuate more.

that sound great. they should display the rates better. Its sad that there is no way to transfer fast USD from one exchange to another. otherwise u could buy BTC at Bitfinex and sell at gadx and vise versa.

marketcup is difference from exchange site into other if your place or country have demand exchange site will be high and other low

sometime difference between north and east of country more than 2000$.

also sites and channel give you average

I also can't understand where the Coinmarketcap takes its quotes. Maybe CMC gives an average value from different crypto-exchanges.
If you go to a specific cryptocurrency, there are quotes from different exchanges depending on the sales volume.

Bitcoin is a speculative effort that many people bring together to bring a price for the coin. Coinmarketcap is an estimate based on an exchange price or the total supply of the coin.
