I don't think that such exchange will be my only criteria when choosing coins to invest at, though I still don't do altcoin investment for now. CoinMarketCap provides more data that one can use as a criteria than just mainly the coin itself. Saying that a coin pumps is like a red flag for me to invest actually, as most likely that word will always derive from "pump and dump" scheme and that wouldn't be for long-term investment for sure. Hate to burst your bubble there, mate.
