4.5 is a nice rating. Happy to see datum project getting the credit they deserve.
And this kind of ratings always make good impact on investors
The rating is good for a project, but not always it determines the success of one, some scam ICOs got there with good marking, but it ended up attracting investors to the scam, so i personally don't see the rating of an ICO a signal for a good project, only by comparing analysis and checking the team is what tells me a project is good.
Yes I saw on twitter Roger Ver calles bitconnect a scam, even though its listed very high on coinmarketcap. So yeah rating is good for reputation but always do your research before getting yourself into an ICO
