CoinGecko/CoinMarketCap alternative for finding the best and worst performers across any custom date range

We built an app that shows cryptocurrencies on the main page just like CoinGecko and CoinMarketcap, but also with added ability where you can select any range on the chart and get which coins performed best and which performed the worst during that time period.

The basic idea is simple:

1. Select a date range on the chart
2. See the top and worst performers instantly

Link of the website is: https://cointrends.xyz/trends

We’d love to hear feedback from everyone.

Is this something you would use when researching market moves and altcoin strength/weakness?

Also what other features do you guys feel CoinMarketCap and CoinGecko are missing?
