Can I suggest you add the data sources for your analysis and charts (assuming you produce them yourself).

For example, you mention that Gridcoin has declined -5,16% in the last 7 days but if I look at CoinMarketCap (https://coinmarketcap.com/currencies/gridcoin/) and take 30-apr/11:00 UTC to 7-May/11:00 UTC it is -1.8% (although I know it could be completely different if I would take it an hour later :) )
