Anyone can advice if this could be good investment for the next 2 years ?
Surprisingly I'm just hearing about this coin of recent and I wouldn't be advising anyone to buy into an altcoin that has been around for years yet it's unknown. There's a reason why people don't know about it for so long and that's because they're not good compared to their counterparts in the marke, if not by now they should have been highlighted..
Having just zero fees or been a privacy focused coin isn't just a enough. If you're going to explore the altcoin market then you have to put some things into consideration like marketing power of the project because there are so many out their that if you don't market your project, it's unlikely to succeed.
The marketing should be to backup the project and not to overtake it in the sense that it becomes the whole focus of the project instead of working on its utility.
