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
Your right there is a big similarity with the coinmarketcap in terms of the interface platform. But I don't know how
long this platform will stand here, because for sure you need to establish and build your community first.
And that would be a very hard time to spend before you gonna have a big community, if you can able to build
community that's the question just like CMC. Good luck anyway dude.
