I think Waves are hidden gem. Many people don't even know how good it is or they don't know team's work well. Waves platform is at least as good as NEO which is excessively advertised and hyped. Is there any list of ICO's which will have Waves platform?
I agree with you on the hidden gem part and that most people do not know how good the tech of Waves is. Waves lacks under a good application which proves its mass capableness as so many projects do (also NEO). To shine out of such competitors like NEO or Ethereum there must be at least one good implementation.
