I also didn't heard about this coins and i never invest on them, i think the best bet was either choose top altcoins or just hold the bitcoin because is the best bet you can.
The fact is that here Altcoins are very much focused on the weight of the cryptocurrency market. If the market shows a positive upward trend, top-top altcoins also go up. But if you take into account other coins, they can also display in their price the degree of their development, as well as the degree of public interest in this project.
