usually coins are compared to each other by marketcap.
it is a metric used to determine the total value of a particular cryptocurrency. It is calculated by multiplying the total number of coins or tokens in circulation by the current market price of one coin or token.
The market cap of a cryptocurrency can give an indication of its relative size and importance compared to other cryptocurrencies. A higher market cap generally indicates that a cryptocurrency is more widely adopted and has a higher level of liquidity.
It is important to note that Market cap is not a measure of the financial performance of a cryptocurrency, but it can be used as an indicator of its popularity and adoption. Also, Market cap can be misleading as it doesn't take into account the circulating supply, so a low market cap coin with a high circulating supply could have a higher value than a high market cap coin with a low circulating supply.
don't worry if a coin isn't among top10

nothing to worry about.
the main thing about a coin > does it have a community, utility and is it actually used now

.. everything else is irrelevant
