As I been looking at altcoins recently I think only two come to mind Litecoin and aurora
Based on my 12 months of research, I think probably what we'll see by end of 2015 is a top four consisting of Bitcoin (BTC), Goldcoin (GLD), Litecoin (LTC), and Dogecoin (DOGE).
LOL, nice trolling. Goldcoin is a scam and dead, Litecoin is failing because it's about to get taken over be ASIC's, and Dogecoin is like a toy coin, only for people new to cryptos and it's dying slowly...
