The interface was exactly the same on the index page of coinmarketcap.com.
And for the feature of user can give ratings based on their favorites, I think that would be misleading since anyone can just put a random star rating on it.
For example, lowered coins can have lots of stars compare to those top coins.
Is similar but not the same, i'm using bootstrap is like that is used in many site also, but i intend change it.
The idea is the user let review about the cryptos, is about a feelings about it, nothing professional
But it may mislead newbies if they later get used to the site and I think will be better if you do the rating according to each crypto 24hours trading volume. Besides, it will also inform the newbies about the coin thats gain more accumulation and likely more price surge in the market.
