I don't see any chance in WAVES to replace the Ethereum. WAVES will not replace Ethereum's position and its popularity ever. WAVES is a good coin, and we treat it good. But comparing with ETH is irrelevant to me. When ETH went to the third position, many people talked ETH days end, now Ripple, EOS, WAVES' time. Because those coins are their favorite or they do trade with these coins, otherwise there is no chance in these coins to replace Ethereum. This is my personal observation though.
