Other website that could be more good than coinmarketcap is coincheckup.com, because this website also offer fundamental analysis every coin and token, and for technical analysis i always used tradingview.com. Both website is really help to decide which coin should to buy and what level price should to buy and sell.
Thank you for the site you suggested. Maybe I will try your webpage research say. Hopefully the site will have the correct analysis to help me choose the potential penny
