It's probably because their circulating supply isn't clear. Even the owners themselves don't know the answer
From:
https://hex.com/faq/Only guesses can be made as it's a function of how many people claim, when they claim, how many were referred. The bonuses paid increase the supply. The circulating supply is a function of how many coins are staked, also impossible to predict. Over 50% of coins staked seems like a reasonable guess because of all the great bonuses paid only to stakers.

As far as i know, Hexcoin is not even supposed to be ranked anywhere.
Questions are;
1. Why are you still using coinmarketcap? Most of their information is inaccurate.
Coingecko nailed it. You can't calculate marketcap when you don't know what the circulating supply is which means coinmarketcap is lying to us.
This is what coingecko did and it was the right move
2. Why do you invest in coins that are not even transparent enough to show details of their circulating supply?
