ORE brings features from other coins like their difficulty adjustment and using them to hopefully address the shortfalls that major coins are dealing with. They got recently listed on Cryptopia, now they are working on IOS and Android wallets.
While searching about this coin, I found a youtube video on it.
Coin: Interzone
Rank: none (https://coinmarketcap.com/currencies/interzone/)

This coin has promising features and what they are looking to address. They consider themselves a social media coin, but the big feature is encrypted messaging. If they can get that working well, there is a big market for it. As Steem does not have a working messaging system as far as a know, besides sending comments in transactions. Though at the moment they are not listed on many exchanges, so time will tell what happens with this coin.

CRS is attempting to address the need for a stable economy in Brazil, many countries in South America are dealing with massive hyperinflation and banking issues.
