On my opinion, of course, waves is only a temporary solution. Ethereum is much more powerful than waves. The applications that can be built on ether vastly outperforms those on waves. And there are lot's of other differents, which made ETH the better one.
True, in altcoin the ethereum is best coin which can compete to the bitcoin. When the time that all atlcoin is dumping the bitcoin is choice of other to earn profit and now in altcoin that which the best improvement is the ethereum and waves price are not to too much recovered from the past price.
Etherium is not only the best coin that can compete in bitcoin because even waves can also do it , to the fact that waves is also a big platform with many developments and improvements on the past ever since it was introduced in the public although etherium is always on the mainstream as most of the ico's had to partner thru it in order for them to make a token or coin. Overall waves isnt still left behind and for sure it will also bloom in the near future.
