Radium [RADS] will implement Smart contracts based on nStratis protocol next year and sitting @ mcap $18m and cur price 5$ having ONLY 3.4m coins current supply.
The main benefit that's the core Radium protocol will be easily maintainable, as well as easily extensible and auditable by the expanding community of C# .NET developers. New features which do not require integration into the core network can be developed using smart contracts.
I am also a big fan (and investor) of Radium. They are technically advanced and I appreciate that developers know very well where to steer the coin. Unfortunately, they lack marketing which would target simple investors (as for example me) without knowing all the technical background.
Lack of marketing it's the current area of improvement, devs understand the importance of this activity and will focus on it in 2018
