Was using a script to calculate this, so I've decided to make a website that's more easy to use. The idea is to track the market making a portfolio of cryptos that reflect each coin market cap https://en.wikipedia.org/wiki/Index_fund.

Really interesting website indexing is the best way to invest and I made a spreadsheet to do more or less what your website is doing, but yours is more advanced since you can scrape the data and have this nice looking interface, I will suggest that you add ranges, you can exclude specific crypto but maybe it could be easier for the user if he could select a range of his choosing, like the 11 to 35, excluding the first 10 coins, that excludes the most solid coins and generates more risk but the chances of bigger profits go up. https://cryptoindexportfolio.com/
