Does any one thinks that Ethereum can survive with the rising of Waves? I've heard that "Waves will be the next Ethereum"
No one here will give you a serious answer, everyone just talks their book.
ETH is much bigger and more establihsed than Waves. I can't really comment on the technical differences of the two, because I am not a technical person.
Waves has more space to rise in price, but might not rise. ETH has more room to fall, but is also down 33% in the last few weeks, so could regain that. Basically you have to do you own research and decide which is better. Even if you decide correctly, the market is often irrational, so you might lose money on a good investment.
