Most of the rating sites make fake rating of a new project which is misleading for the investors. I don't rely on any rating site. If an investor depends on rating, surely he will fall in trap. He should invest on his own research not depending such fake ratings. High rating projects sometimes make scam. So every investor should be aware of it before investment.
Be aware of what you do and only believe in your research because it will help you greatly reduce unnecessary risks. I will often search for project news and ask relevant questions to make sure the project is profitable for me. However, it is not always convenient because if the market suddenly drops, the coins you invest can make you lose.
Well, there is no doubt that's because bitcoin banned in china and still in Asia's many countries don't support bitcoin. So they made that chart their own way.
