Interesting blog. I was about to start a similair discussion. There's a lot of exchanges out there. I found that coinmarketcap.com gives quite a decent overview. I really advice people to take a look at: https://www.coincheckup.com They give great insights in the team, the product, advisors, community, the business and the business model and other techincal insights. For example: https://www.coincheckup.com/coins/Gulden#analysis For a complete Gulden Investment and research analysis.
