Now in the market there are about one thousand coins which have both common features, and distinctions. But if you compare, as well as you, it is better because of one factor therefore a half of coins has to eat other half. They develop and compete and will continue to live if they have support.
although waves can be classified as strong coins, and have great potential, I think it is still very difficult to make it beyond the ETH. even ETH also has advantages that can even be equivalent bitcoin.
I do not think that it will happen ever. People know and trust Ethereum more than Waves (which is also a very good altcoin). Probably, waves will be even growing faster this year, but it will not overcome ETH.
