2017 Majority of the altcoins reaches their all-time high and 2018 is a big turn around some coins hit their bottom low, what is this big factor or major update that can get make all the coins to reach their all-time high again.
i think that it is obvious - we need a huge pump of BTC market or at least to see a turning around on the chart, and that's all what we need to start growing again and maybe reaching their new ATH.
