Crypto Index

I'd like to create a site like [login to view URL] which essentially - Creates a price based on the rules in the PDFs on the site - Lists + tracks the underlying constituents within it - Tracks the total market cap, volume from exchanges and so on - Includes charts ( you can use [login to view URL] as an example ) - Should be real-time (propose what needs to be used e.g. [login to view URL]) - Features like this are also nice additions [login to view URL]
