I think most of such links and articles are paid posts so we cannot go with their analysis as they will post anykind of shilling for any project if you pay them, the quality projects are only found by research and analysis, among the ongoing icos i like konios, payera and tokenunion.
In this case post is not paid, icoguide.com has advertising services, but they are not related to the blog. All content in the blog is the personal opinion of expert bloggers.
