In my opinion bitcoin is winner of this year. Although bitcoin price decrease in the starting of this year and Etherum has improved then before but still bitcoin price is high then that of Ethereum. So this thing make bitcoin winner. Another thing is bitcoin value. Because of its higher value many people first choice is bitcoin in case of investment. Etherum also improved its price but it still less then that of bitcoin. Bitcoin also have more user then that of Ethereum and this thing is due to bitcoin growing popularity.
