At this point why you don't make clear which are the coinmarketcap and volume needed to get the coin listed in the op? So who really wants to get the coin inside the website knows that have to reach tot market cap and tot volume on exchanges...
It's not only the market cap, thats merely one of the many factors taken into consideration.
We might overlook a market cap if the rest of the factors are pushing us towards adding the coin.
On the other hand, if a coin has few else to provide, we might be firm on the market cap.
One way or another, the market cap does make it more likely to get a coin featured, but its not a fixed yes-no line.
