Many traders prefer Coinmarketcap.com but I think these sites are much better:
1.
https://bitscreener.com: I like this site because it shows you a small window that you can know the daily-gainers. This property will be excellent for anyone looking for Bump/dump shit coins
2.
https://cryptowat.ch: Combines all charts in one place "more than one currency for more than one trading platform."
The colors and interface are convenient for the eye
