Does any one thinks that Ethereum can survive with the rising of Waves? I've heard that "Waves will be the next Ethereum"
I don't think there is anything on a market that can beat Ethereum, I would not even compare the two.
EThereum has many unique features and has its own niche, plus there are much more projects that are based off Ethereum
Your opinion is wrong, unfortunately.
Because if you will look closely and will study the features of Komodo Coin, it can offer faster transaction per second (TPS) and offers a very low gas price compared to eth. It can also generate tokens from its platform. 
It is one of the most undervalued coin but has the big possibility to surpass eth or even BTC.
