Ratings agency Weiss Ratings has issued a response to recent grades it awarded to various cryptos, following on from the crypto community\'s negative response. Many in the community were most outraged by the lowly C+ rating awarded to Bitcoin. In a new blog post, the ratings agency defended the C+ that they gave the well-known crypto.

The company asserted that their main aim was to provide advice and guidance to investors looking to invest, and as such, they provided advice based on what the most stable and reliable investment choice would be. Because of this, the rating was predominantly based on the price volatility of the coin.

Those that criticised the rating felt that it should not be based purely on Bitcoin\'s volatility. Several people commented that they felt that the ratings should reflect the success of the coin and how advanced and unproblematic its design was. 

The Weiss Cryptocurrency Ratings were reportedly dictated by four key indexes. The first, \"Investment Reward\", highlighted Bitcoin\'s crashing market value in recent weeks. They also evaluated \"Investment Risk\", and gave Bitcoin a poorer rating based on its recent volatility. They then measured its \"Fundamentals\", covering areas such as security and popularity. Bitcoin scored poorly for network capacity and centralisation. Finally, they rated Bitcoin based on \"Technology\", and gave it a lower score due to its sustainability and scalability.
