How are those cryptocurrencies ranked in the price charts in Coinmarketcap, Bitscreeneer, Coingecko? Based on what criteria?
Why are there more expensive cryptocurrencies in lower positions than the ones above?
The default ranking of CMC is by marketcap, from the name of the site itself. It is primarily showing rankings based on how much a certain project is valued. Other details are also shown though. Market cap is basically computed as price per coin in circulation times the total circulating supply.
The prices of coins do not matter that much in terms of ranking because of their circulating supply. Even if a certain coin is valued at 1 cent only if it has a much larger circulating supply than the coin which is valued at 1 USD, it will still have a higher market cap. If a coin is valued at 1,000 USD and has only 10 circulating supply, it will still remain at the bottom.
