The Weiss ratings are actually not as negative as they sound! Weiss uses a different rating model than we're used to. I found this excerpt on their site:
"Caveat 1. Do not misunderstand the Weiss Ratings scale. Other rating agencies use a scale from triple A to single C. In that scheme a B grade is “junk” and a C is close to failure. In contrast, Weiss Ratings’ B is “good” and C is “fair.” Based on a study of the Weiss Ratings by the U.S. Government Accountability Office, an institution is not categorized “vulnerable” unless its grade is D+ or lower."
After reading this part it puts a whole different spin on the ratings. You can read more about how they came to these ratings over here.
P.S. I was scrolling through the list of crypto authors, looking for new ones to add to my feed. I checked out your profile after reading this and saw you write about crypto too, so I added you to my follow list.
I too write about crypto a lot. Perhaps you'd like to take a look at my profile as well and see if there's anything there that suits your fancy?
