It is more interesting when an ICO is using a Ethereum contract, waves is a very good project, and their dex is very good too, but it is difficult to use it since it is a little big buggy. But i see that a lot of ICO's are using Waves technology to develop their coins, and a lot of them are having success. I think that more people needs to accostumbrate to use Waves, it is a very promising one, and a new way to develop coins.
