Polo has so many shit coins, why you want ICN on it?
Why I want ICN on it? The question is why not? What bad thing could happen if ICN would be listed there? These are the questions ... not you try and find a decent answer
Iconomi is investment fund, and they will start their own service where people can put money in. ICN doesn't need to be on Polo but Polo will beg to have ICN for trade.
