It's finally in motion. Let's hope it breaks out towards new highs today. ETC is the best Top 20 coin you can hold for 2018 for maximum gains. Other top 20 options for growth potential are BTC, ADA, NEO, XRP, EOS, XMR and LSK. If you want high risk/high reward, small cap coins like GNO, ANT, JNT, SNT etc is the way to go.
