Ethereum will survive even in Pump of Bitcoin or some other altcoin.
and for me Ethereum is easy to use than Waves
Ethereum is maybe easier to use as it has been for longer at the crypto community, but don't forget that Waves team is very experienced and are doing a great work.
Waves has a big feature that the ethereum network doesn't.
Waves enables Decentralized exchange( As it is, an exhcange that is not being controlled by anyone, it is being controlled by the people, which makes it much more safer and also enables very low fee trading).
Also don't forget that Waves market cap is smaller then the Ethereum one, and has a larger place to grow.
