I would start with the main coins and do them well. I think you are trying to bite off too much. Start of with BTC - it's in the media the most and is talked about the most. You can add Ethereum, EOS, Monero, etc later.
Then have a list of the "best" predictions of Bitcoin. I.e. Bob Lee (made up name) says "$25,000 by March 2019".
My main problem with your site is that I don't think you can rank these people with your formula. There is a lot that goes into it - their reputation (some guy vs crypto hedge fund manager), their number of roughly successful predictions, how many predictions they have made (success ratio), etc.
I know this is very generic, but hopefully it helps a little bit.
