Crypto rankings are needed to perform analysis and convince us to see what type of coin we are going to buy. But not based on confidence in the rating, it must be true that we stick to the development of the coin, not the rating.
I totally agree with you. Crypto ratings can be beneficial if we know how to use it. I personally take crypto rating as a preference to do my own researches. However, it is important to choose which crypto rating site we will use. Because many crypto rating sites are manipulated by developers that rate their projects unrealistically. You're right that we should stick to the developments of the coin itself!
