man, how hard to understand.
polo is not listing any ethereum tokens. not one of them.
they are an exchange, so they cant handle dividends payment anyway.
on the other hand they are usa based. if they sell tokens on their platform, which represent a stakeholder value, they are screwed from the regulatory side, because they dont have the license to do that - Kraken do.
Aaaand what about REP (augur)
?which makes not much sense though. REP functions mostly the same as ICN, so it can't be for legal reasons
Yes of course, it's not due legal reasons. I still think that it is due the NDA between iconomi and poloniex, there isn't any other possible valid reason.
