I think the website that you provide is very useful to be able to see the difference in the price of bitcoin from various exchange places so I can make it easier for traders to be able to profit from a variety of existing markets, what if you can add a variety of coins in 10 the big one in coinmarketcap is enough.
I think it will be very convenient in trading because you can know exactly what price level is happening in this market. I have used Coinmarketcap but the data at this site is often very different so I don't use it much recently. I personally consider using this site in the near future because the value of Bitcoin is very similar to the data at big exchanges.
In addition, you can use TradingView to be easier to analyze if you have experience in trading because this is a site with lots of detailed reviews and will be of great help to you.
