Frequently Asked Questions
What is OpenMarketCap?
OpenMarketCap is a token price tracker.
Where does the data come from?
Directly from API of exchanges.
Why did the volume suddenly jump on July 3?
We added new exchanges. The reported volume is the aggregate across exchanges.
Why is this data different from CMC?
There are three reasons why token prices may differ on OMC and CMC:
Listing fees - CMC currently excludes exchanges without fees. BitThumb is a major exchange that falls into this
category. Prices reported by these exchanges are included on OMC.
All exchange data - The
price of BCD (bitcoin diamond) on CoinMarketCap is an interesting case study. The highest volume exchange
to trade BCD is Binance. However, the Binance price is excluded from the average price because it is an outlier.
With OMC, we want to avoid one off rules. Until we can apply a consistent set of rules, we will include all
exchanges in the pricing calculations.
Smaller marketcap tokens - The variability in pricing is highest for thinly traded tokens. NetCoin is one example:
Price of NetCoin on CMC vs
Price of NetCoin on OMC. The 600x difference between prices is entirely due to which exchanges are included
in the price calculation.
What are your rules for determining the ranking?
Tokens are ranked by marketcap, which is the circulating supply * price (marketcap)
Tokens without any trading volume in the past 24 hours are excluded from the ranking.
What are your rules for calculating token prices?
The average price for each token is the volume-weighted average across exchanges
To get the price per exchange in USD, we first find the token's price in BTC. We then determine the fiat (USD,
EUR, JPY, KRW, USDT) price for BTC on that exchange.
