Coinmarketcap launched in 2013 and cryptocurrencies as well as the interest in them have grown significantly since then. In 2013, they were tracking only seven cryptocurrencies on a handful of exchanges with a total market cap of only about $1.7 billion.
Currently there are over 1,800 cryptocurrencies with a market cap of $214 billion and over 210 exchanges. According to earlier data collected this year, Coinmarketcap was the 174th most visited website according to Amazon's Alexa with over 60 million visits at this time. It seems that there is still plenty of room for growth and that this market is still very new.
Coinmarketcap also recently recreated their logo to show the ups and downs in the crypto market, and I barely even noticed the logo change at first. Coinmarketcap currently has over 460k followers on their Twitter account. Also, Coinmarketcap has an IOS app where you can add cryptos to your watchlist to easily see the most relevant data to you.
It's important to understand if you're getting accurate information about the cryptos you want to invest in as Coinmarketcap has gotten a few things wrong at times. However, they are still the most reliable source of crypto prices and new coin listings as far as I know, and its good to be able to see them they change their logo or update their UI/UX interface as we want them to continue to provide us with accurate and reliable data.
