After gaining some recognition on Wall Street, cryptocurrencies have attracted the interest of asset rating agencies.

Last week, Florida-based Weiss Ratings released a report that assigned grades to dozens of cryptocurrencies based on a number of metrics, like risk, technological innovation, and other fundamentals.

There were a couple of surprises to the report. One of them was that none of the cryptocurrencies rated received an “A.” Another surprise was that Ethereum received a higher grade than Bitcoin and Ripple.

How trustworthy are Weiss ratings? Investment and cryptocurrency experts are divided.

“Very trustworthy,” says David Drake, a crypto asset expert. “It is the first step for more ratings to come out on cryptocurrencies.”

“The mere fact that futures exchanges and rating services have finally legitimized investment in cryptocurrencies after nine years of their existence is a strong sign of trend maturation,” adds Elliot Prechter, Head of Computer Analysis, Elliot Wave. “It is reminiscent of the timing of gold legalization, which occurred at an interim peak in gold that saw it fall in half thereafter.”

“Weiss has been around for a while and appears to be respected,” says  Al Zdenek, president of Taust Sollus Wealth Management. “From their past history, they appear to tend to come out with new rankings or ratings in different areas of the markets first.  The current ranking of cryptocurrencies seems to be the latest one.”
