Waves will implement a decentralized asset exchange which will include a crypto exchange! No more need for websites you can buy/sell assets(e.g. crpytos) on the blockchain! Sasha is a genius! 
I'm very disappointed as well. A listing on Poloniex is perceived by many as an "endorsement" for a solid project.
Waves is a potential threat to the Poloniex business model.
Am I the only one who is worried by Sasha's tweets about polo and ETC? I am not saying at all if he is right or wrong. Some say polo will never list waves after such tweets but I think that the fact that polo wont list waves has already been known to Sasha for some time now. So it is not like he 'started a war", like someone mentioned, I think it is more like he knows waves wont be on polo so he has no reservations to say what he thinks is right.
This worries me. It's not like polo is a make it or break it for every coin but it surely is important. I mean, is there even 1 coin in the history of cryptocurrency that is doing well an isn't listed on polo? Hopefully it is not like this but I'm still thinking that the reason why Sasha is so direct is becasue he might have some confirmation that waves wont be on polo so now he is free to speak his mind. Otherwise, I dont see the reason why would one want to piss off polo moderators.
