I put a url in my profile to the telegram group of GELDC.

It is the biggest coin in terms of marketcap and not in terms of price and coinmarketcap and coingecko
list coins which have a lower marketcap than Bitcoin and Ethereum and all the other top 100 coins, because
they are heavily invested in Bitcoin and Ethereum and would loose all their investments if GELDC would appear
at top 1 at these 2 pages (now you know the reason they don´t list the biggest marketcap coin!).

Although i have information that an other marketcap page will list it within this month and
then GELDC dethrones Bitcoin from top 1.

The chain is ETH chain and it is an erc20 token.

GELDC does not much to rule the markeetcap, because it simply rules it already as top1 coin
with its marketcap.
