My husband still uses CoinMarketCap, but when he sees things go up and he's thinking of trading, he also visits the exchange he wants to use and cross references with toher exchagnes, like BIttrex and Binance, as the MarkyMark mentioned. I think that's what I'm going to have to do too from now on. I needed to trade anyway, because I needed to pay some bills, but I do feel like a noob for not double checking on the actual exchange site.
