maybe because of the volume 24 hours the coins have in the exchange
if you look at
CMC they have just 10$
Yeah, same thing I suspect, I know that exchange delist coins based on the volume this coin have in their market, this is because most of this exchange have to run the full node of all the coins they have on their exchange and this way pay huge amount of money monthly just to make sure they keep the server running so that there won't be an experience of any downtime from their network, this coins are delisted in order for them not to spend unnecessary money paying for their hosting and the coin is worthless and not recognized by anyone. Delisting is a norm with exchanges.
