I don't think Waves is a rival to Ethereum or Neo.. Waves's decentralized exchange is really unsuccessful. I am very sorry to invest in Waves last year.
Then what DEX are you using my friend? I can tell you that there is no DEX like the Waves DEX, as i tried out all of them out. Both in daily volume and user exprerience Waves DEX is unmatched. It will take time for mass adoption as 95% of people in crypto do not even know what a DEX is and why it's superior to centralized exchanges. In some time SC and AS will be available on the Waves platform, so that also ERC20 tokens can be traded.
