I have seen something strange for me, it has to do with the data of these 2 sites being very different, I do not understand the reason of this and for that I would like someone to explain to me

worldcoinindex:


look at the percentage changes of each currency

coinmarketcap


look at the percentage changes of each currency

here is my thought regarding this problem.
it can be happen like this because coinmarketcap and worldcoinindex summarized it all with different perspective.
i mean like this :
[For Example]
coinmarketcap make a percentage based on every trade happened in every exchanger that offer you BTC/USD and others pair.
worldcoinindex make a percentage based on top exchanger that offering BTC/USD and others pair.

of course it will be different if they do this,because sometimes we will see a gap between a top exchanger and side exchanger.
only small people doing a trade in side exchanger and most people doing it in top exchanger,
because of that the gap between buy and sell will be a bit huge and because of that the percentage that showed will be different

coinmarketcap make a percentage based on every trade happened in every exchanger that offer you BTC/USD and others pair.
worldcoinindex make a percentage based on top exchanger that offering BTC/USD and others pair.

may be this, last week I was doing ETH trade and every two hours I checked ETH price at coinmarketcap, I do this to avoid being in and out of exchange all the time

What happened:

I saw the ETH price was $338, two hours later I went to see it again and the ETH price was $ 338, two hours later I went to see it and the ETH price was $338, only after a long time I realized that I had a problem with the coinmarketcap that the price of ETH was not changing and on that day I lost money because I do day trade.

ok that was episode of the ETH

then happened to XRP this time I really lost money because I had done some technical analysis and indicated that I would have some XRP dump next day I went to coinmarketcap.com and it was okay, that was my mistake.

in fact the price had fallen and I lost money

Two days ago it was with lisk

Never rely on coinmarketcap or worldcoinindex if you are day trader and just rely on price  on exchange platforms where you do trading.

Price or percentage changes on both of the above site can be different because they might be using api from two different exchange platforms or taking average price from different platforms. This makes a lot of difference in price....

Don't rely on any ticker service, use blockfolio like app to keep updated about your total crypto assets holding and trade accordingly.

I check coinmarketcap to check which coin is traded in which exchanges and nothing else. You can never trust both of the sites mentioned. If you have coins in an exchange then be there and know the details about that coin. Sometimes coinmarketcap prices are too deceitful.

If you must use coin market cap, drill down to "Markets" of the price you are looking at. You would see the details which makes up the Price you see. There is usually a difference in price based on the pairs and exchanges. I have seen coin make gains of 100% plus to only ETH or only LTC and nor to BTC and in reversed order too.

my mobile phone has problems, since i made an accident i still have not bought another mobile phone. but i save the name of this app. i will install when I have new mobile phone.

and thanks for the advice.

Sometimes coinmarketcap prices are too deceitful.

altcoin when they fall cause a huge loss so the person must be constantly monitor the market and the news

it seems that technical analysis does not work on altcoins and everything about good news (price increase) and bad news (price falls)


I have seen coin make gains of 100% plus to only ETH or only LTC and nor to BTC and in reversed order too.

they must have a lot of work to keep coinmarketcap, this should make them very tired... well I do not blame them




I had to spend hours on the computer just looking at coinmarketcap, they delay putting the current prices of the coins.

for example when lisk is at $6.20 at coinmarketcap it is still at $5.90.

this other site (worldcoinindex) the data is updated instantly

That is simply because of the pairs which Coinmarketcap and Worldcoinindex lists.

WorldCoinIndex lists on the BTC/USD pairs-site the biggest exchanges for this pair (example) while Coinmarketcap lists on the BTC/USD pair up to 400 markets/pairs and compares every price of the pairs with its average crypto-currency price (example). The only things that is interesting on Coinmarketcap are the BTC/USD pairs.

Like the other users said, the price varies from exchange to exchange because of their fees, regulation or trading volume etc.

Coinmarketcap lists all possible related trading pairs with Lisk. The exchange 51szzc reports the price $5.41 for the pair LSK/CNY while BitBay reports $6.61 for the pair LSK/USD.

Ok looks like you based on two mentioned site to check for prices for your trading monitoring activity purposes. Both sites are general and have different based sources on their posted price in every coin.

What you must do next time is to track prices of your coins at their respective exchanges since whatever posted on coinmarketcap or worldcoinindex, still the price based will be on the trading platform when you are playing with your coins. Sounds hassle but we are used on the scenarios like that by using any kinds of device platform.

Anyway as suggested above, blockfolio is a good tool for mobile although currently like you stated, you can't install it at the moment.

I'm more comfortable with coinmarketcap, maybe because that I was familiar with it for years and didn't saw a similar one that showed in the best way like CMC.

The worldcoinindex seems good too, but I lose the orientation where to look and what to expect, I think they should work more in UI and UX.

That may happen because coinmarketcap and worldcoinindex use different API, different software to calculate trading volume and maybe different exchanges too. We know cryptocurrencies prices always different in some exchanges.
In that case, you shouldn't depend on coinmarketcap to watch over the prices, maybe you forgot to refresh the page, that's why eth price ddidn'e change, always $338. Just check the prices on exchanges or trading platform where you buy and sell ethereum, the exchange rate will be accurate.

Hi,

I have a good experience in both of them. The main different thing is the percentage of worldcoinindex that is showed and reset or restarted from 00:00 UTC.

The second difference is the trade volume from the list of exchange markets, worldcoinindex doesn't calculate or include all/some world major coin exchanges such as "Binance" missing in Bitcoin volume. It means that the trade volume amount in worldcoinindex is fewer than coinmarketcap twice,

As a result, the average price differs from coinmarketcap a little.



The example of worldcoinindex price calculated time reset/restarted:

1. if you live in London, UTC+1 (Time in worldcoinindex will be reset at 1:00 AM London Time m means UTC+1), therefore, it will use the price at this time (UTC 00:00) to compare with every minute price changed of the entire day (24hr) and showing you the percentage has changed from this time. it is totally different from coinmarketcap which is using the last 24hour of that coin to be compared with the current price.
Note: the percentage will be compared with the price at UTC 00:00. London means 1:00 AM (UTC+1), Bangkok means 7:00 AM (UTC+7), Korea means 9:00 AM (UTC+3)

2. The average price of worldcoinindex is calculated from some exchanges not all, coinmarketcap looks cover almost all main exchanges. however the graph in worldcoinindex looks easier to understand the line of the graph.

Normally I see the graph in worldcoinindex .

Hope it help.

At first there is a  chance that those websites are counting the average price based on different exchanges (maybe worldcoinindex also count korean exchanges, duno). The other thing is that the prices on CMC are updated much slower. Just a couple minutes ago I've seed 1:1 rate with a difference in 24h % change. But then worldcoinindex prece changed automaticaly to the updated oned while CMC rates remained the same after several page updates. Just choose a trustworthy exchange and aim on its rates.

Simply because the price/value are based on different exchanges, like what other being said above posts. While coinmarketcap getting its average price on 21 mostly all exchanges which were the BCD listed while worldcoinindex only have 10 smaller base in number exchanges and obviously the price will differ from each other. And I will always recommend coinmarketcap to be the most accurate price in every coin.

Here's the catch: Neither sites mention the sources from which they derive the price of tokens from and just end up penning it as 'based on an average from various sites'. Since there is measurable variance in many listed coins as compared on both sites, both of them can simply not be used as a reliable source for pricing. Referring to multiple exchanges for the latest price would be the way to go rather than looking up the above sites but for general purpose reference its just fine.
