Polo seem to give high hopes that Waves value is going to rise more if if its listed. Polo guarantees the token to be trustworthy that investors get to buy more.
If Polo isn't listing anything after DAO, why didn't they even announce anything or even just reply to any messages sent to them.
They don't make those kinds of announcements. They never have and they probably never will. They only announce that they are listing a coin shortly before they list or more often at the time of listing.
Acceptable enough but they should have at least responded to the request or maybe even replied to this thread explaining something.
One of their support replied to the ANN ICO thread when the coin displayed their logo. check here https://bitcointalksearch.org/topic/m.15506092
They have responded multiple times by saying they don't discuss coin additions.
