Ethereum just has the head start and the main developer share. Waves is very good in its own right, and its time will come.
It would be tough to be Ethereum it's same like bitcoins no one can beat these coins yet.Rising of waves is temporary rise but investing in waves could be profitable.I think many people trust ethereum unlike waves.Ethereum has potential to grow more and in future it could cost a lot,it's the best coin after bitcoins.
