If I'm given the chance to study altcoins for long term investment, I would go for some coins that are under $0.20 in value. The ones that I am looking forward to study are Electroneum, Dogecoin, Tron, Reddcoin, Bytecoin, Siacoin, Dent, Digibyte and a lot more.

I'm currently holding ETN, DOGE and TRON, and still have yet to buy other coins who are under $0.20. These undervalued coins would probably skyrocket in the long run.
