People like to simplify things and talk about the death of bitcoin and the take over of the alt coins . I think there is room for both in 2018 . We have seen a enormous growth in cryptocurrency market cap. I predict this market cap to grow a lot during the year , and its really needed right now is see almost the same capital moving around to earn money on the pump and dumps. Its true that bit coin is facing major challenges regarding scaling issues and high transaction fees . But also remember that bit coin has proved it self numerous times , and has survived many dips and crashes . I call this year the year of virtual gold.By this i mean that bit coin will be the currency people flee to when times are uncertain . I will hodl my coins but of course diversify with some of the alt coins . happy new year
