Ethereum, Waves and ARDR are my favorite cons for 2018. I expect some big moves in the future
etherium is my all time favourite and i think it will provide good in the end. along with ETH. i am looking forward to ripple and "IOTA" as well i am investing all my earning into these 3 and hoping for their great return in the near future. my first strategy is to invest in "iota" and ripple as much as i can and than i comes to ethereum because the chances to gain more profit is in those two.
