"The chart below shows that, of the top cryptocurrencies by market capitalization, some - like EOS, Cardano, Monero, and Bitcoin - have had a lot more commits than others - like Populous or Bitconnect". Since Bitconnect is a now defunkt ponzi scheme and not a cryptocurrency, their lack of Github activity makes sense :) This analysis would be more helpful if the author properly curated the projects / tokens to include in the study.
