I disagree. A coin doesn't have to be listed on coinmarketcap to be of value or service.
With a lot of coins, their sole purpose is seemingly to manipulate the price and total supply in order to achieve an inflated ranking on the page. Outside of the top 10-20 coins, ranking on coinmarketcap isn't necessarily an indicator of a coin's overall usefulness or actual value.
Plus when you take into consideration that the coin itself resides on 7 different blockchains, its total "market cap" value is split up 7 different ways. And by design, none of the different .XHY tokens are meant to have a higher or lower value than one another, I'm pretty sure...
