I know they make an average of all the exchanges out there.
Let's take Ripple for exemple. It currently lists @ $3.05 on CoinMarketCap right now. However the XRP/USD pairs trade at roughly $2.6-2/7 on Binance, Bittrex, Kraken, HitBTC etc. Literally no exchange trade XRP/USD anywhere close from $3.05.
So I guess my question is how can they list XRP à $3.05 when all the other exchanges trade it at $2.7? Does that mean that CoinMarketCap also add all the XRP/BTC, XRP/ETH pairs into the equation, convert them in $ and make an average out of it?
Thanks!
They take the average price of all exchange.
