I have never cared for Weiss. (As you get what you pay for... and since Weiss doesn't charge the clients, they are getting money from elsewhere, and that influences things)

But, it is generally a good place to start.

I agree with no crypto being an A. How can anything in its infancy be an A rating? We haven't even gotten started in cryptos. Even the much loved block chain will have several additions to it that will make it FAR BETTER.

So, we will see how Weiss responds in the future.
I am sure that many cryptos will be as money, and so their ratings will be A. Will Weiss accurately rate them?
